pub trait BitArray {

Expand description

A trait which allows numbers to act as fixed-size bit arrays

Required Methods§

Source

fn bit(&self, idx: usize) -> bool

Is bit set?

Source

fn bit_slice(&self, start: usize, end: usize) -> Self

Returns an array which is just the bits from start to end

Source

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

Bitwise and with n ones

Source

fn trailing_zeros(&self) -> usize

Trailing zeros

Source

fn zero() -> Self

Create all-zeros value

Source

fn one() -> Self

Create value representing one

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.
