Struct InMemoryDistributedCache 

pub struct InMemoryDistributedCache { /* private fields */ }

An in-memory reference DistributedCache — a concurrent map with TTL.

Share one instance between multiple Cache instances (via Arc) to simulate several nodes pointing at the same L2 within one process.

Implementations

impl InMemoryDistributedCache

pub fn new(clock: Arc<dyn Clock>) -> Self

Creates an empty backend using the given clock for TTL accounting.

Trait Implementations

impl Clone for InMemoryDistributedCache

fn clone(&self) -> InMemoryDistributedCache

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl DistributedCache for InMemoryDistributedCache

fn get<'life0, 'life1, 'async_trait>( &'life0 self, key: &'life1 str, ) -> Pin<Box<dyn Future<Output = Result<Option<Vec<u8>>>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Reads the bytes stored at key, if present and unexpired.

fn set<'life0, 'life1, 'async_trait>( &'life0 self, key: &'life1 str, value: Vec<u8>, ttl: Option<Duration>, ) -> Pin<Box<dyn Future<Output = Result<()>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Writes value at key with an optional TTL.

fn remove<'life0, 'life1, 'async_trait>( &'life0 self, key: &'life1 str, ) -> Pin<Box<dyn Future<Output = Result<()>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Removes key.
