Trait WrappingAbsAssign 

pub trait WrappingAbsAssign {
    // Required method
    fn wrapping_abs_assign(&mut self);
}

Replaces a number with its absolute value, wrapping around at the boundary of the type.

Required Methods

fn wrapping_abs_assign(&mut self)

Dyn Compatibility

This trait is dyn compatible.

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

Implementations on Foreign Types

impl WrappingAbsAssign for i8

fn wrapping_abs_assign(&mut self)

Replaces a number with its absolute value, wrapping around at the boundary of the type.

$$ x \gets \begin{cases} |x| & \text{if} \quad x > -2^{W-1}, \\ -2^{W-1} & \text{if} \quad x = -2^{W-1}, \end{cases} $$ where $W$ is Self::WIDTH.

Worst-case complexity

Constant time and additional memory.
