Read-only access to a bitmap’s chunks and metadata.

Required Methods

fn complete_chunks(&self) -> usize

Return the number of complete (fully filled) chunks.

fn get_chunk(&self, chunk: usize) -> [u8; N]

Return the chunk data at the given absolute chunk index.

fn last_chunk(&self) -> ([u8; N], u64)

Return the last chunk and its size in bits.

fn pruned_chunks(&self) -> usize

Return the number of pruned chunks.

fn len(&self) -> u64

Return the total number of bits.

Provided Methods

fn is_empty(&self) -> bool

Returns true if the bitmap is empty.

fn pruned_bits(&self) -> u64

Return the number of pruned bits (i.e. pruned chunks * bits per chunk).

fn get_bit(&self, bit: u64) -> bool

Return the value of a single bit.

fn ones_iter_from(&self, pos: u64) -> OnesIter<'_, Self, N>

where Self: Sized,

Returns an iterator over the indices of set bits starting from pos.

If pos falls within a pruned region, iteration starts at the first unpruned bit instead.

fn ones_iter_range(&self, range: Range<u64>) -> OnesIter<'_, Self, N>

where Self: Sized,

Returns an iterator over the indices of set bits in range.

Iteration starts at the first unpruned bit at or after range.start and stops before the smaller of range.end and the bitmap length. Empty or reversed ranges yield no bits.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
