Struct arrow::util::bit_chunk_iterator::BitChunks

source ·
pub struct BitChunks<'a> { /* private fields */ }
Expand description

Iterates over an arbitrarily aligned byte buffer

Yields an iterator of u64, and a remainder. The first byte in the buffer will be the least significant byte in output u64

source§

impl<'a> BitChunks<'a>

source

pub const fn remainder_len(&self) -> usize

source

pub const fn chunk_len(&self) -> usize

Returns the number of chunks

source

pub fn remainder_bits(&self) -> u64

Returns the bitmask of remaining bits

source

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