Struct UnalignedBitChunk

pub struct UnalignedBitChunk<'a> { /* private fields */ }

Iterates over an arbitrarily aligned byte buffer

Yields an iterator of aligned u64, along with the leading and trailing u64 necessary to align the buffer to a 8-byte boundary

This is unlike BitChunkIterator which only exposes a trailing u64, and consequently has to perform more work for each read

Implementations

impl<'a> UnalignedBitChunk<'a>

pub fn new(buffer: &'a [u8], offset: usize, len: usize) -> Self

pub fn lead_padding(&self) -> usize

Returns the number of leading padding bits

pub fn trailing_padding(&self) -> usize

Returns the number of trailing padding bits

pub fn prefix(&self) -> Option<u64>

Returns the prefix, if any

pub fn suffix(&self) -> Option<u64>

Returns the suffix, if any

pub fn chunks(&self) -> &'a [u64]

Returns reference to the chunks

pub fn iter(&self) -> UnalignedBitChunkIterator<'a>

Returns an iterator over the chunks
