Trait CastUnsigned 

pub trait CastUnsigned: Sized {
    type Unsigned;

    // Required method
    fn cast_unsigned(self) -> Self::Unsigned;
}

Reinterprets a signed integer’s bits as its unsigned counterpart.

For value-checked conversion to the unsigned counterpart, use CheckedCast / SaturatingCast / StrictCast with the unsigned target type.

Required Associated Types

type Unsigned

The unsigned counterpart type (e.g. u32 for i32).

Required Methods

fn cast_unsigned(self) -> Self::Unsigned

Returns the bit pattern of self reinterpreted as its unsigned counterpart (two’s complement: negative values become large).

use const_num_traits::CastUnsigned;

assert_eq!(CastUnsigned::cast_unsigned(-1i8), 255u8);
assert_eq!(CastUnsigned::cast_unsigned(127i8), 127u8);

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
