}

Trait for signed integers corresponding to the ones satisfying Index.

Always smaller than or equal to isize.

Required Associated Constants

const MAX: Self

Maximum representable value.

Required Methods

fn truncate(value: usize) -> Self

Truncate value to type Self.

fn zx(self) -> usize

Zero extend self.

fn sx(self) -> usize

Sign extend self.

Provided Methods

fn sum_nonnegative(slice: &[Self]) -> Option<Self>

Sum nonnegative values while checking for overflow.

Object Safety

This trait is not object safe.
