Expand description

Module level cache entry.

Implementations§

source§

impl<'config> ModuleCacheEntry<'config>

source

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

Create the cache entry.

source

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.

source

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.
