Struct tidb_query_datatype::codec::data_type::BitVec

pub struct BitVec {
    data: Vec<u64>,
    length: usize,
}

A boolean vector, which consolidates 64 booleans into 1 u64 to save space.

BitVec is mainly used to implement bitmap in ChunkedVec.

Fields

data: Vec<u64>

length: usize

Trait Implementations

impl Clone for BitVec

fn clone(&self) -> BitVec

Returns a copy of the value.

pub fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for BitVec

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq<BitVec> for BitVec

fn eq(&self, other: &BitVec) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &BitVec) -> bool

This method tests for !=.
