Trait BitMask

pub trait BitMask {
    const LEN: usize;

    // Required methods
    fn first_offset(&self) -> usize;
    fn before(&self, rhs: &Self) -> bool;
    fn as_little_endian(&self) -> Self;
    fn all_zero(&self) -> bool;
    fn clear_high_bits(&self, n: usize) -> Self;
}

Trait for the bitmask of a vector Mask.

Required Associated Constants

const LEN: usize

Total bits in the bitmask.

Required Methods

fn first_offset(&self) -> usize

get the offset of the first 1 bit.

fn before(&self, rhs: &Self) -> bool

check if this bitmask is before the other bitmask.

fn as_little_endian(&self) -> Self

convert bitmask as little endian

fn all_zero(&self) -> bool

whether all bits are zero.

fn clear_high_bits(&self, n: usize) -> Self

clear high n bits.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
