Struct ContentCache 

pub struct ContentCache { /* private fields */ }

Thread-safe content cache with TTL-based eviction.

Uses RwLock<HashMap> — reads only acquire a read lock (no contention between concurrent resolves). Writes acquire a write lock (infrequent: only on cache miss or invalidation).

Data is stored behind Arc so cache hits return a cheap reference-counted pointer instead of cloning the entire document.

Implementations

impl ContentCache

pub fn new(ttl: Duration) -> Self

Create a new cache with the given TTL.

pub fn get(&self, key: &str) -> Option<Arc<Vec<u8>>>

Get cached content if it exists and hasn’t expired. Returns an Arc<Vec<u8>> — cheap clone (reference count bump only).

pub fn insert(&self, key: String, data: Vec<u8>)

Insert or update a cache entry.

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

Invalidate a cache entry (call on publish/delete).

pub fn evict_expired(&self)

Remove all expired entries (call periodically from cleanup thread).
