Struct BitVec

pub struct BitVec { /* private fields */ }

A dynamically sized compact bit vector with a fixed block size of 64 bits.

Implementations

impl BitVec

pub fn new(bit_capacity: usize) -> Self

Creates a new BitVec with the specified bit capacity.

pub fn set_bit_count_and_clear(&mut self, bit_count: usize)

Sets the bit count of the BitVec and clears all bits.

If the new bit count exceeds the current block capacity, the block capacity is increased.

pub fn set(&mut self, index: usize)

Sets the bit at the specified index.

Panics

Panics if the new bit count exceeds the current block capacity with debug_assertions enabled.

pub fn set_and_grow(&mut self, index: usize)

Sets the specified bit and grows the BitVec if necessary.

pub fn grow(&mut self, new_block_count: usize)

Resizes the BitVec to the specified number of blocks.

If the new block count exceeds the current capacity, the capacity is increased by half. The blocks are not cleared.

pub fn unset(&mut self, index: usize)

Unsets the bit at the specified index.

pub fn get(&self, index: usize) -> bool

Gets the bit at the specified index.

Returns false if the index is out of bounds or the bit is unset.

pub fn block_capacity(&self) -> usize

Returns the block capacity of the BitVec.

pub fn block_count(&self) -> usize

Returns the block count of the BitVec.

pub fn count_ones(&self) -> usize

Returns the number of set bits in the BitVec.

pub fn count_zeros(&self) -> usize

Returns the number of unset bits in the BitVec.

pub fn clear(&mut self)

Clears all bits in the BitVec.

pub fn blocks(&self) -> Blocks<'_>

Returns an iterator over the blocks of the BitVec.

pub fn or(&mut self, other: &Self)

Performs an in-place bitwise OR operation with another BitVec.
