Struct MemoryCache 

pub struct MemoryCache { /* private fields */ }

In-memory cache — the default backend. Cheap to Arc-clone.

Implementations

impl MemoryCache

pub fn new() -> Self

Create an empty cache.

pub async fn len(&self) -> usize

Number of cached responses.

pub async fn is_empty(&self) -> bool

true if no responses are cached yet.

Trait Implementations

impl CacheBackend for MemoryCache

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

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

Return the cached response for key, if any.

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

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

Persist resp under key. Overwrites any previous value.

impl Clone for MemoryCache

fn clone(&self) -> MemoryCache

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Default for MemoryCache

fn default() -> MemoryCache

Returns the “default value” for a type.
