Struct AtomicBitVec 

pub struct AtomicBitVec<O: Overflow = NoOverflow> { /* private fields */ }

An atomic bit-vector.

By default the vector has a fixed size, and setting a bit past its end panics. AtomicBitVec<Growable> instead grows to hold that bit, which appends storage rather than reallocating it, so that a word handed out to a thread stays valid while another thread grows the vector.

Implementations

impl<O: Overflow> AtomicBitVec<O>

pub fn new(nbits: u64) -> Self

Creates a new AtomicBitVec holding at least nbits bits, all set to false.

pub fn test_and_set_range(&self, start_bit: u64, end_bit: u64) -> u64

Sets the bits between start_bit (included) and end_bit (excluded), and returns the number of bits that were already set. A growable vector grows to hold end_bit.

pub fn to_vec(&self, nbits: u64) -> Vec<bool>

Copy the first nbits bits. Test only.
