Implementations

impl MemoryStorage

pub fn new() -> Self

pub fn clear(&self)

Clear all stored data

pub fn shard_count(&self) -> usize

Get the number of stored shards

pub fn metadata_count(&self) -> usize

Get the number of stored metadata entries

Trait Implementations

impl Default for MemoryStorage

fn default() -> Self
