Struct CboRoaringBitmapCodec

pub struct CboRoaringBitmapCodec;

A conditionnal codec that either use the RoaringBitmap or a lighter ByteOrder en/decoding method.

Implementations

impl CboRoaringBitmapCodec

pub fn serialized_size(roaring: &RoaringBitmap) -> usize

pub fn serialize_into_vec(roaring: &RoaringBitmap, vec: &mut Vec<u8>)

pub fn serialize_into_writer<W: Write>( roaring: &RoaringBitmap, writer: W, ) -> Result<()>

pub fn deserialize_from(bytes: &[u8]) -> Result<RoaringBitmap>

pub fn intersection_with_serialized( bytes: &[u8], other: &RoaringBitmap, ) -> Result<RoaringBitmap>

pub fn merge_into<I, A>(slices: I, buffer: &mut Vec<u8>) -> Result<()>

where I: IntoIterator<Item = A>, A: AsRef<[u8]>,

Merge serialized CboRoaringBitmaps in a buffer.

if the merged values length is under the threshold, values are directly serialized in the buffer else a RoaringBitmap is created from the values and is serialized in the buffer.

pub fn merge_deladd_into<'a>( deladd: &KvReader<DelAdd>, previous: &[u8], buffer: &'a mut Vec<u8>, ) -> Result<Option<&'a [u8]>>

Merges a DelAdd delta into a CboRoaringBitmap.
