Struct ModuleCacheEntry

pub struct ModuleCacheEntry<'config>(/* private fields */);

Module level cache entry.

Implementations

impl<'config> ModuleCacheEntry<'config>

pub fn new(compiler_name: &str, cache_config: &'config CacheConfig) -> Self

Create the cache entry.

pub fn get_data<T, U, E>( &self, state: T, compute: fn(_: &T) -> Result<U, E>, ) -> Result<U, E>

where T: Hash, U: Serialize + for<'a> Deserialize<'a>,

Gets cached data if state matches, otherwise calls compute.

Data is automatically serialized/deserialized with bincode.

pub fn get_data_raw<T, U, E>( &self, state: &T, compute: fn(_: &T) -> Result<U, E>, serialize: fn(_: &T, _: &U) -> Option<Vec<u8>>, deserialize: fn(_: &T, _: Vec<u8>) -> Option<U>, ) -> Result<U, E>

where T: Hash,

Gets cached data if state matches, otherwise calls compute.

If the cache is disabled or no cached data is found then compute is called to calculate the data. If the data was found in cache it is passed to deserialize, which if successful will be the returned value. When computed the serialize function is used to generate the bytes from the returned value.
