}

A generic cache for storing and loading compiled wasm modules.

Associated Types

Required methods

unsafe fn load(
    &self,
    store: &Store,
    key: Hash
) -> Result<Module, Self::DeserializeError>

Loads a module using the provided Store and [Hash].

Safety

This function is unsafe as the cache store could be tampered with.

fn store(
    &mut self,
    key: Hash,
    module: &Module
) -> Result<(), Self::SerializeError>

Store a Module into the cache with the given [Hash].
