Struct Atomic 

pub struct Atomic { /* private fields */ }

A fixed-length bitmap whose bits can be set concurrently through shared references.

Atomic::set uses relaxed ordering, which is published by ownership transfer rather than by the operations themselves: the bits can only be read back by consuming the map (Atomic::into_bitmap), so whatever reclaims exclusive ownership from the setters (joining their tasks, Arc::into_inner) is what makes their writes visible.

Implementations

impl Atomic

pub fn zeroes(len: u64) -> Self

Create a bitmap of len zero bits.

pub fn set(&self, bit: u64)

Set bit to 1.

Panics

Panics if the bit doesn’t exist.

pub fn into_bitmap(self) -> BitMap

Convert into a BitMap holding the same bits.

Taking self by value means the caller already reclaimed exclusive ownership from every setter, which is the synchronization that makes their relaxed writes visible.
