Expand description

Cache for individual segment byte buffers.

Caches are optional and operate above a SegmentSource. They should only store host buffers: device buffers and other non-host handles should be passed through uncached.

Required Methods§

Source

fn get<'life0, 'async_trait>( &'life0 self, id: SegmentId, ) -> Pin<Box<dyn Future<Output = VortexResult<Option<ByteBuffer>>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait,

Return a cached segment, or None on cache miss.

Source

fn put<'life0, 'async_trait>( &'life0 self, id: SegmentId, buffer: ByteBuffer, ) -> Pin<Box<dyn Future<Output = VortexResult<()>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait,

Store a segment in the cache.

Dyn Compatibility§

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
