 /// Trait for fallible conversions between `bnum` integer types.
 ///
 /// Unfortunately, [`TryFrom`] cannot currently be used for conversions between `bnum` integers, since [`TryFrom<T> for T`](https://doc.rust-lang.org/std/convert/trait.TryFrom.html#impl-TryFrom%3CU%3E-for-T) is already implemented by the standard library (and so it is not possible to implement `TryFrom<BUint<M>> for BUint<N>`). When the [`generic_const_exprs`](https://github.com/rust-lang/rust/issues/76560) feature becomes stabilised, it may be possible to use [`TryFrom`] instead of `BTryFrom`. `BTryFrom` is designed to have the same behaviour as [`TryFrom`] for conversions between two primitive types, and conversions between a primitive type and a bnum type. `BTryFrom` is a workaround for the issue described above, and so you should not implement it yourself. It should only be used for conversions between `bnum` integers.
