Calculates the length of an Option<String> as an Option<usize>\nwithout moving the String. The map method takes the self argument by value,\nconsuming the original, so this technique uses as_ref to first take an Option to a\nreference to the value inside the original.
let text: Option<String> = Some(\"Hello, world!\".to_string());\n// First, cast `Option<String>` to `Option<&String>` with `as_ref`,\n// then consume *that* with `map`, leaving `text` on the stack.\nlet text_length: Option<usize> = text.as_ref().map(|s| s.len());\nprintln!(\"still can print text: {text:?}\");Converts from &mut Option<T> to Option<&mut T>.
let mut x = Some(2);\nmatch x.as_mut() {\n Some(v) => *v = 42,\n None => {},\n}\nassert_eq!(x, Some(42));Returns a slice of the contained value, if any. If this is None, an\nempty slice is returned. This can be useful to have a single type of\niterator over an Option or slice.
Note: Should you have an Option<&T> and wish to get a slice of T,\nyou can unpack it via opt.map_or(&[], std::slice::from_ref).
assert_eq!(\n [Some(1234).as_slice(), None.as_slice()],\n [&[1234][..], &[][..]],\n);The inverse of this function is (discounting\nborrowing) [_]::first:
for i in [Some(1234_u16), None] {\n assert_eq!(i.as_ref(), i.as_slice().first());\n}Returns a mutable slice of the contained value, if any. If this is\nNone, an empty slice is returned. This can be useful to have a\nsingle type of iterator over an Option or slice.
Note: Should you have an Option<&mut T> instead of a\n&mut Option<T>, which this method takes, you can obtain a mutable\nslice via opt.map_or(&mut [], std::slice::from_mut).
assert_eq!(\n [Some(1234).as_mut_slice(), None.as_mut_slice()],\n [&mut [1234][..], &mut [][..]],\n);The result is a mutable slice of zero or one items that points into\nour original Option:

assert_eq!(Some(123).as_mut_slice().first_mut(), Some(&mut 123))Returns the contained Some value, consuming the self value.
Panics if the value is a None with a custom panic message provided by\nmsg.
let x = Some(\"value\");\nassert_eq!(x.expect(\"fruits are healthy\"), \"value\");let x: Option<&str> = None;\nx.expect(\"fruits are healthy\"); // panics with `fruits are healthy`We recommend that expect messages are used to describe the reason you\nexpect the Option should be Some.
let item = slice.get(0)\n .expect(\"slice should not be empty\");Hint: If you’re having trouble remembering how to phrase expect\nerror messages remember to focus on the word “should” as in “env\nvariable should be set by blah” or “the given binary should be available\nand executable by the current user”.
\nFor more detail on expect message styles and the reasoning behind our\nrecommendation please refer to the section on “Common Message\nStyles” in the std::error module docs.
Returns the contained Some value, consuming the self value.
Because this function may panic, its use is generally discouraged.\nInstead, prefer to use pattern matching and handle the None\ncase explicitly, or call unwrap_or, unwrap_or_else, or\nunwrap_or_default.
Panics if the self value equals None.
let x = Some(\"air\");\nassert_eq!(x.unwrap(), \"air\");let x: Option<&str> = None;\nassert_eq!(x.unwrap(), \"air\"); // failsReturns the contained Some value or a provided default.
Arguments passed to unwrap_or are eagerly evaluated; if you are passing\nthe result of a function call, it is recommended to use unwrap_or_else,\nwhich is lazily evaluated.
assert_eq!(Some(\"car\").unwrap_or(\"bike\"), \"car\");\nassert_eq!(None.unwrap_or(\"bike\"), \"bike\");Returns the contained Some value or a default.
Consumes the self argument then, if Some, returns the contained\nvalue, otherwise if None, returns the default value for that\ntype.
let x: Option<u32> = None;\nlet y: Option<u32> = Some(12);\n\nassert_eq!(x.unwrap_or_default(), 0);\nassert_eq!(y.unwrap_or_default(), 12);Returns the contained Some value, consuming the self value,\nwithout checking that the value is not None.
Calling this method on None is undefined behavior.
let x = Some(\"air\");\nassert_eq!(unsafe { x.unwrap_unchecked() }, \"air\");let x: Option<&str> = None;\nassert_eq!(unsafe { x.unwrap_unchecked() }, \"air\"); // Undefined behavior!Maps an Option<T> to Option<U> by applying a function to a contained value (if Some) or returns None (if None).
Calculates the length of an Option<String> as an\nOption<usize>, consuming the original:
let maybe_some_string = Some(String::from(\"Hello, World!\"));\n// `Option::map` takes self *by value*, consuming `maybe_some_string`\nlet maybe_some_len = maybe_some_string.map(|s| s.len());\nassert_eq!(maybe_some_len, Some(13));\n\nlet x: Option<&str> = None;\nassert_eq!(x.map(|s| s.len()), None);Calls the provided closure with a reference to the contained value (if Some).
let v = vec![1, 2, 3, 4, 5];\n\n// prints \"got: 4\"\nlet x: Option<&usize> = v.get(3).inspect(|x| println!(\"got: {x}\"));\n\n// prints nothing\nlet x: Option<&usize> = v.get(5).inspect(|x| println!(\"got: {x}\"));Returns the provided default result (if none),\nor applies a function to the contained value (if any).
\nArguments passed to map_or are eagerly evaluated; if you are passing\nthe result of a function call, it is recommended to use map_or_else,\nwhich is lazily evaluated.
let x = Some(\"foo\");\nassert_eq!(x.map_or(42, |v| v.len()), 3);\n\nlet x: Option<&str> = None;\nassert_eq!(x.map_or(42, |v| v.len()), 42);Computes a default function result (if none), or\napplies a different function to the contained value (if any).
\nlet k = 21;\n\nlet x = Some(\"foo\");\nassert_eq!(x.map_or_else(|| 2 * k, |v| v.len()), 3);\n\nlet x: Option<&str> = None;\nassert_eq!(x.map_or_else(|| 2 * k, |v| v.len()), 42);A somewhat common occurrence when dealing with optional values\nin combination with Result<T, E> is the case where one wants to invoke\na fallible fallback if the option is not present. This example\nparses a command line argument (if present), or the contents of a file to\nan integer. However, unlike accessing the command line argument, reading\nthe file is fallible, so it must be wrapped with Ok.
let v: u64 = std::env::args()\n .nth(1)\n .map_or_else(|| std::fs::read_to_string(\"/etc/someconfig.conf\"), Ok)?\n .parse()?;Transforms the Option<T> into a Result<T, E>, mapping Some(v) to\nOk(v) and None to Err(err).
Arguments passed to ok_or are eagerly evaluated; if you are passing the\nresult of a function call, it is recommended to use ok_or_else, which is\nlazily evaluated.
let x = Some(\"foo\");\nassert_eq!(x.ok_or(0), Ok(\"foo\"));\n\nlet x: Option<&str> = None;\nassert_eq!(x.ok_or(0), Err(0));Transforms the Option<T> into a Result<T, E>, mapping Some(v) to\nOk(v) and None to Err(err()).
let x = Some(\"foo\");\nassert_eq!(x.ok_or_else(|| 0), Ok(\"foo\"));\n\nlet x: Option<&str> = None;\nassert_eq!(x.ok_or_else(|| 0), Err(0));Converts from Option<T> (or &Option<T>) to Option<&T::Target>.
Leaves the original Option in-place, creating a new one with a reference\nto the original one, additionally coercing the contents via Deref.
let x: Option<String> = Some(\"hey\".to_owned());\nassert_eq!(x.as_deref(), Some(\"hey\"));\n\nlet x: Option<String> = None;\nassert_eq!(x.as_deref(), None);Converts from Option<T> (or &mut Option<T>) to Option<&mut T::Target>.
Leaves the original Option in-place, creating a new one containing a mutable reference to\nthe inner type’s Deref::Target type.
let mut x: Option<String> = Some(\"hey\".to_owned());\nassert_eq!(x.as_deref_mut().map(|x| {\n x.make_ascii_uppercase();\n x\n}), Some(\"HEY\".to_owned().as_mut_str()));Returns an iterator over the possibly contained value.
\nlet x = Some(4);\nassert_eq!(x.iter().next(), Some(&4));\n\nlet x: Option<u32> = None;\nassert_eq!(x.iter().next(), None);Returns a mutable iterator over the possibly contained value.

Arguments passed to and are eagerly evaluated; if you are passing the\nresult of a function call, it is recommended to use and_then, which is\nlazily evaluated.
let x = Some(2);\nlet y: Option<&str> = None;\nassert_eq!(x.and(y), None);\n\nlet x: Option<u32> = None;\nlet y = Some(\"foo\");\nassert_eq!(x.and(y), None);\n\nlet x = Some(2);\nlet y = Some(\"foo\");\nassert_eq!(x.and(y), Some(\"foo\"));\n\nlet x: Option<u32> = None;\nlet y: Option<&str> = None;\nassert_eq!(x.and(y), None);Returns None if the option is None, otherwise calls f with the\nwrapped value and returns the result.
Some languages call this operation flatmap.
\nfn sq_then_to_string(x: u32) -> Option<String> {\n x.checked_mul(x).map(|sq| sq.to_string())\n}\n\nassert_eq!(Some(2).and_then(sq_then_to_string), Some(4.to_string()));\nassert_eq!(Some(1_000_000).and_then(sq_then_to_string), None); // overflowed!\nassert_eq!(None.and_then(sq_then_to_string), None);Often used to chain fallible operations that may return None.
let arr_2d = [[\"A0\", \"A1\"], [\"B0\", \"B1\"]];\n\nlet item_0_1 = arr_2d.get(0).and_then(|row| row.get(1));\nassert_eq!(item_0_1, Some(&\"A1\"));\n\nlet item_2_0 = arr_2d.get(2).and_then(|row| row.get(0));\nassert_eq!(item_2_0, None);Returns None if the option is None, otherwise calls predicate\nwith the wrapped value and returns:
Some(t) if predicate returns true (where t is the wrapped\nvalue), andNone if predicate returns false.This function works similar to Iterator::filter(). You can imagine\nthe Option<T> being an iterator over one or zero elements. filter()\nlets you decide which elements to keep.
fn is_even(n: &i32) -> bool {\n n % 2 == 0\n}\n\nassert_eq!(None.filter(is_even), None);\nassert_eq!(Some(3).filter(is_even), None);\nassert_eq!(Some(4).filter(is_even), Some(4));Returns the option if it contains a value, otherwise returns optb.
Arguments passed to or are eagerly evaluated; if you are passing the\nresult of a function call, it is recommended to use or_else, which is\nlazily evaluated.
let x = Some(2);\nlet y = None;\nassert_eq!(x.or(y), Some(2));\n\nlet x = None;\nlet y = Some(100);\nassert_eq!(x.or(y), Some(100));\n\nlet x = Some(2);\nlet y = Some(100);\nassert_eq!(x.or(y), Some(2));\n\nlet x: Option<u32> = None;\nlet y = None;\nassert_eq!(x.or(y), None);Returns the option if it contains a value, otherwise calls f and\nreturns the result.

let items = vec![0_u16, 1, 2];\n\nlet res: Option<Vec<u16>> = items\n .iter()\n .map(|x| x.checked_add(1))\n .collect();\n\nassert_eq!(res, Some(vec![1, 2, 3]));As you can see, this will return the expected, valid items.
\nHere is another example that tries to subtract one from another list\nof integers, this time checking for underflow:
\n\nlet items = vec![2_u16, 1, 0];\n\nlet res: Option<Vec<u16>> = items\n .iter()\n .map(|x| x.checked_sub(1))\n .collect();\n\nassert_eq!(res, None);Since the last element is zero, it would underflow. Thus, the resulting\nvalue is None.
Here is a variation on the previous example, showing that no\nfurther elements are taken from iter after the first None.
let items = vec![3_u16, 2, 1, 10];\n\nlet mut shared = 0;\n\nlet res: Option<Vec<u16>> = items\n .iter()\n .map(|x| { shared += x; x.checked_sub(2) })\n .collect();\n\nassert_eq!(res, None);\nassert_eq!(shared, 6);Since the third element caused an underflow, no further elements were taken,\nso the final value of shared is 6 (= 3 + 2 + 1), not 16.
Returns a consuming iterator over the possibly contained value.
\nlet x = Some(\"string\");\nlet v: Vec<&str> = x.into_iter().collect();\nassert_eq!(v, [\"string\"]);\n\nlet x = None;\nlet v: Vec<&str> = x.into_iter().collect();\nassert!(v.is_empty());Takes each element in the Iterator: if it is a None, no further\nelements are taken, and the None is returned. Should no None\noccur, the sum of all elements is returned.
This sums up the position of the character ‘a’ in a vector of strings,\nif a word did not have the character ‘a’ the operation returns None:
let words = vec![\"have\", \"a\", \"great\", \"day\"];\nlet total: Option<usize> = words.iter().map(|w| w.find('a')).sum();\nassert_eq!(total, Some(5));\nlet words = vec![\"have\", \"a\", \"good\", \"day\"];\nlet total: Option<usize> = words.iter().map(|w| w.find('a')).sum();\nassert_eq!(total, None);try_trait_v2)Residual type.

This multiplies each number in a vector of strings,\nif a string could not be parsed the operation returns None:
let nums = vec![\"5\", \"10\", \"1\", \"2\"];\nlet total: Option<usize> = nums.iter().map(|w| w.parse::<usize>().ok()).product();\nassert_eq!(total, Some(100));\nlet nums = vec![\"5\", \"10\", \"one\", \"2\"];\nlet total: Option<usize> = nums.iter().map(|w| w.parse::<usize>().ok()).product();\nassert_eq!(total, None);try_trait_v2)? when not short-circuiting.try_trait_v2)FromResidual::from_residual\nas part of ? when short-circuiting.
