Struct google_cloud_bigquery::storage::util::bit_chunk_iterator::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) -> UnalignedBitChunk<'a>

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

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

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

pub fn iter( &self ) -> Chain<Chain<IntoIter<u64>, Cloned<Iter<'a, u64>>>, IntoIter<u64>>
