Trait for a data structure for storing count ranks.

Required methods

fn build(count_ranks: Vec<usize>) -> Box<Self>

Builds a RankArray from a sequence of count ranks.

fn serialize_into<W: Write>(&self, writer: W) -> Result<usize>

Serializes the data structure into the writer.

fn deserialize_from<R: Read>(reader: R) -> Result<Box<Self>>

Deserializes the data structure from the reader.

fn size_in_bytes(&self) -> usize

Gets the number of bytes to serialize the data structure.

fn memory_statistics(&self) -> Value

Gets breakdowns of memory usages for components.

fn get(&self, i: usize) -> usize

Gets the i-th count rank.

fn len(&self) -> usize

Gets the number of count ranks stored.

fn is_empty(&self) -> bool

Checks if the data structure is empty.
