pub fn size(&self) -> usize

Get the size of bits

pub fn count_ones(&self) -> u32

Get the number of ones

pub fn count_zeros(&self) -> u32

Get the number of zeros

pub fn shl_or(&mut self, x: usize)

Faster left shift and or

bitset | (bitset << x)

pub fn buffer(&self) -> &[u64]

Get inner buffer

pub fn buffer_mut(&mut self) -> &mut [u64]

Get inner buffer with mutable reference

pub fn chomp(&mut self)

Set tailing bits in inner buffer whose index are greater than size to 0
