Source

pub fn cache_metadata(&mut self, cid: String, metadata: ContentMetadata)

Cache content metadata.

Source

Get cached metadata.

Source

pub fn peek_metadata(&self, cid: &str) -> Option<&ContentMetadata>

Get cached metadata without updating statistics (immutable).

Source

pub fn remove_metadata(&mut self, cid: &str) -> Option<ContentMetadata>

Remove metadata from cache.

Source

pub fn clear_cache(&mut self)

Clear all cached metadata.

Source

pub fn cached_count(&self) -> usize

Get the number of cached items.

Source

pub fn stats(&self) -> &ContentManagerStats
