Trait wasmtime::CacheStore
source · [−]pub trait CacheStore: Send + Sync + Debug {

}
Expand description
Implementation of an incremental compilation’s key/value cache store.
In theory, this could just be Cranelift’s CacheKvStore
trait, but it is not as we want to
make sure that wasmtime isn’t too tied to Cranelift internals (and as a matter of fact, we
can’t depend on the Cranelift trait here).
Required methods
Try to retrieve an arbitrary cache key entry, and returns a reference to bytes that were
inserted via Self::insert
before.
