Struct BitVectorBuilder 

pub struct BitVectorBuilder { /* private fields */ }

Mutable bit-vector builder. Word-level mutations stay cheap (Vec<u64> indexed access); call freeze to produce an immutable BitVector.

Mirrors the BytesMut → Bytes and Apache Arrow BooleanBuilder → BooleanArray pattern.

Implementations

impl BitVectorBuilder

pub fn new() -> Self

Creates an empty builder.

pub fn with_capacity(bits: usize) -> Self

Creates a builder with capacity for at least bits bits.

pub fn filled(len: usize, value: bool) -> Self

Creates a builder with all bits set to value, length len.

pub fn zeros(len: usize) -> Self

Creates a builder with all bits set to false.

pub fn ones(len: usize) -> Self

Creates a builder with all bits set to true.

pub fn len(&self) -> usize

Returns the current bit length.

pub fn is_empty(&self) -> bool

Returns whether no bits have been pushed.

pub fn get(&self, index: usize) -> Option<bool>

Gets the bit at the given index (read access during build).

pub fn set(&mut self, index: usize, value: bool)

Sets the bit at the given index.

Panics

Panics if index >= len().

pub fn push(&mut self, value: bool)

Appends a bit to the end.

pub fn freeze(self) -> BitVector

Freezes the builder into an immutable BitVector.
