Struct HttpResponseCache 

pub struct HttpResponseCache { /* private fields */ }

In-memory (method, url, body_hash) → JSON value cache with TTL.

Cheap to clone (Arc-wrapped internals); each enricher instance keeps its own clone in its hot path, and the daemon may share instances across enricher reload cycles when the config has not changed.

Implementations

impl HttpResponseCache

pub fn new(ttl: Duration) -> Self

Build a new cache with the given TTL.

A ttl of zero is treated as “disabled” — every lookup returns CacheOutcome::Miss and inserts are no-ops, so call sites can always go through the cache without checking cache_ttl > 0.

pub fn is_disabled(&self) -> bool

Returns true when this cache is “off” (TTL is zero).

pub fn ttl(&self) -> Duration

Configured TTL.

pub fn lookup(&self, key: &CacheKey) -> (CacheOutcome, Option<Value>)

Look up key. Returns the cached value if it is present and within TTL; expires it lazily otherwise.

pub fn insert(&self, key: CacheKey, value: Value)

Insert value under key. No-op when the cache is disabled.

pub fn evict_expired(&self) -> usize

Remove every entry whose stored_at + TTL is in the past. Called periodically by a background sweep when the daemon’s enrichment pipeline has at least one cache configured.

pub fn stats(&self) -> (u64, u64, u64)

Snapshot the cumulative cache stats since construction.

pub fn len(&self) -> usize

Number of entries currently held.

pub fn is_empty(&self) -> bool

True when no entries are held.

Trait Implementations
