[dependabot]

Bumps github.com/holiman/uint256 from 1.2.0 to 1.2.2.

Release notes

Sourced from github.com/holiman/uint256's releases.

Will Hunting (v1.2.2)

What's Changed

• Interfaces to work nicely with fastssz by @​karalabe in holiman/uint256#126
• String conversion from decimal by @​elee1766 and @​holiman in holiman/uint256#122 and holiman/uint256#127
• Nice constructions via MustFromBig, MustFromHex and MustFromDecimal by @​karalabe and @​holiman in holiman/uint256#128, holiman/uint256#131
• Implement PrettyDec and native Dec by @​holiman in holiman/uint256#130
• Optimize AddMod by @​jwasinger in holiman/uint256#120

New API-methods

Methods to create Ints

// FromDecimal is a convenience-constructor to create an Int from a
// decimal (base 10) string. Numbers larger than 256 bits are not accepted.
func FromDecimal(decimal string) (*Int, error) 
// MustFromBig is a convenience-constructor from big.Int.
// Returns a new Int and panics if overflow occurred.
func MustFromBig(b *big.Int) *Int
// MustFromHex is a convenience-constructor to create an Int from
// a hexadecimal string.
// Returns a new Int and panics if any error occurred.
func MustFromHex(hex string) *Int
// MustFromDecimal is a convenience-constructor to create an Int from a
// decimal (base 10) string.
// Returns a new Int and panics if any error occurred.
func MustFromDecimal(decimal string) *Int

Methods to initialize Int instances

// SetFromDecimal sets z from the given string, interpreted as a decimal number.
// OBS! This method is _not_ strictly identical to the (*big.Int).SetString(..., 10) method.
// Notable differences:
// - This method does not accept underscore input, e.g. "100_000",
// - This method does not accept negative zero as valid, e.g "-0",
//   - (this method does not accept any negative input as valid))
func (z *Int) SetFromDecimal(s string) (err error)
// SetFromHex sets z from the given string, interpreted as a hexadecimal number.
// OBS! This method is not strictly identical to the (*big.Int).SetString(..., 16) method.
// Notable differences:
// - This method require "0x" or "0X" prefix.
// - This method does not accept zero-prefixed hex, e.g. "0x0001"
// - This method does not accept underscore input, e.g. "100_000",
// - This method does not accept negative zero as valid, e.g "-0x0",
