Struct silkenweb::memo::MemoFrame

pub struct MemoFrame(_);

A MemoFrame represents the scope of a frame for the MemoCache.

Implementations

impl MemoFrame

pub fn cache<Key, Value, ValueFn>(&self, key: Key, value_fn: ValueFn) -> Value where
    Key: 'static + Eq + Hash,
    Value: 'static + Clone,
    ValueFn: FnOnce() -> Value, 

Lookup a value in the cache.

If a value is not there, it will be generated using value_fn. All functional dependencies of value_fn should be included in key.

The value will be cached for the next frame, whether it’s new or existing.

It is up to the client to use a key that uniquely identifies the functional dependencies of variables captured by value_fn.
