Crate i256

Optimized implementations of 256-bit signed and unsigned integers.

This contains a fixed-width, performant implementation for 256-bit signed and unsigned integers. This has significantly faster performance for basic math operations than comparable fixed-width integer types, since it can use optimizations from 128-bit integers on 64-bit architectures.

Structs

• I256
  The 256-bit signed integer type.
• I384
  The 384-bit signed integer type.
• I512
  The 512-bit signed integer type.
• I1024
  The 1024-bit signed integer type.
• ParseIntError
  An error which can be returned when parsing an integer.
• TryFromIntError
  The error type returned when a checked integral type conversion fails.
• U256
  The 256-bit unsigned integer type.
• U384
  The 384-bit unsigned integer type.
• U512
  The 512-bit unsigned integer type.
• U1024
  The 1024-bit unsigned integer type.

Enums

• IntErrorKind
  Enum to store the various types of errors that can cause parsing an integer to fail.

Type Aliases

• ILimb
  The same sized type of the limb as a signed integer.
• IWide
  A signed type double the width of the limb.
• ULimb
  The unsigned type used as a native “limb”.
• UWide
  An unsigned type double the width of the limb.
• i256
  The 256-bit signed integer type.
• u256
  The 256-bit unsigned integer type.
