Struct arc_swap::cache::MapCache[−][src]

pub struct MapCache<A, T, F> { /* fields omitted */ }
Expand description

An implementation of a cache with a projection into the accessed value.

This is the implementation structure for Cache::map. It can’t be created directly and it should be used through the Access trait.
