Struct ResponseCache 

pub struct ResponseCache { /* private fields */ }

Thread-safe LRU response cache. get/insert take &self; the Mutex guards the LruCache (whose get needs &mut to bump recency).

Implementations

impl ResponseCache

pub fn new() -> Self

pub fn with_capacity(cap: usize) -> Self

pub fn get(&self, key: &str) -> Option<CacheEntry>

Look up an entry, bumping its recency. Returns a clone so the lock is released before the caller inspects state / rebuilds a response.

pub fn insert(&self, key: String, entry: CacheEntry)

pub fn remove(&self, key: &str)

Drop a single key (used by an SWR refresh that produced an uncacheable result, e.g. a 5xx — see should_cache).

pub fn len(&self) -> usize

pub fn is_empty(&self) -> bool

Trait Implementations

impl Default for ResponseCache

fn default() -> Self

Returns the “default value” for a type.
