Implementations

impl RenderCache

pub fn new() -> Self

New empty cache.

pub fn render<B: Backend>( &mut self, backend: &B, input: &ResourceInput<'_>, ) -> Vec<GeneratedArtifact>

Render via cache: lookup by (backend, resource) content hash; on miss, call the backend through the Morphism interface so artifact provenance is populated, then store.

pub fn stats(&self) -> &CacheStats

Current cache statistics.

pub fn len(&self) -> usize

Number of entries currently cached.

pub fn is_empty(&self) -> bool

Whether the cache is empty.

pub fn clear(&mut self)

Drop all entries (preserves stats).

pub fn invalidate<B: Backend>( &mut self, backend: &B, input: &ResourceInput<'_>, ) -> bool

Remove a specific entry. Returns whether it was present.
