Implementations

impl MemoryCache

pub fn new(default_ttl: u64) -> Self

Creates a memory cache with the provided default TTL in seconds.

Trait Implementations

impl CacheBackend for MemoryCache

fn backend_name(&self) -> &'static str

Returns the stable backend name.

fn health_check<'life0, 'async_trait>( &'life0 self, ) -> Pin<Box<dyn Future<Output = Result<()>> + Send + 'async_trait>>

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

Performs a lightweight backend health check.

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

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

Reads a raw byte value by key.

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

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

Atomically reads and removes a raw byte value by key when supported.

fn set_bytes<'life0, 'life1, 'async_trait>( &'life0 self, key: &'life1 str, value: Vec<u8>, ttl_secs: Option<u64>, ) -> Pin<Box<dyn Future<Output = ()> + Send + 'async_trait>>

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

Writes a raw byte value by key with an optional TTL in seconds.

fn set_bytes_if_absent<'life0, 'life1, 'async_trait>( &'life0 self, key: &'life1 str, value: Vec<u8>, ttl_secs: Option<u64>, ) -> Pin<Box<dyn Future<Output = bool> + Send + 'async_trait>>

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

Writes a raw byte value only when the key is absent.

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

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

Removes a key from the cache.

fn delete_many<'life0, 'life1, 'async_trait>( &'life0 self, keys: &'life1 [String], ) -> Pin<Box<dyn Future<Output = ()> + Send + 'async_trait>>

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

Removes multiple keys from the cache.

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

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

Invalidates every key with the given prefix.
