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.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
