}

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.

Dyn Compatibility

This trait is dyn compatible.

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