Struct InMemoryKeyCache 

pub struct InMemoryKeyCache { /* private fields */ }

Available on crate feature cache-inmemory only.

An in-memory key cache with TTL-based expiration.

Keys are stored in memory and automatically expire after the configured TTL. This implementation is thread-safe and can be shared across tasks.

Examples

use jwk_simple::InMemoryKeyCache;
use std::time::Duration;

// Create a cache with 5-minute TTL
let cache = InMemoryKeyCache::new(Duration::from_secs(300));

// Or use the default TTL
let cache = InMemoryKeyCache::default();

Implementations

impl InMemoryKeyCache

pub fn new(ttl: Duration) -> Self

Creates a new in-memory cache with the specified TTL.

pub fn with_default_ttl() -> Self

Creates a new in-memory cache with the default TTL (5 minutes).

pub fn ttl(&self) -> Duration

Returns the configured TTL.

pub async fn len(&self) -> usize

Returns the number of entries currently in the cache.

Note: This count may include expired entries that haven’t been cleaned up yet.

pub async fn is_empty(&self) -> bool

Returns true if the cache is empty.

Trait Implementations

impl Debug for InMemoryKeyCache

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for InMemoryKeyCache

fn default() -> Self

Returns the “default value” for a type.

impl KeyCache for InMemoryKeyCache

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

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

Gets a key from the cache by its ID.

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

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

Stores a key in the cache.

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

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

Clears all keys from the cache.
