[−][src]Struct dyn_cache::CacheMiss

pub struct CacheMiss<'k, Key: ?Sized, Scope, Input, Output, H = DefaultHashBuilder> { /* fields omitted */ }

The result of a failed attempt to retrieve a value from the cache. Initialize a full CacheEntry for storage with CacheMiss::init.

Implementations

impl<'k, Key: ?Sized, Scope, Input, Output, H> CacheMiss<'k, Key, Scope, Input, Output, H>[src]

pub fn init<R>(
    self,
    input: Input,
    query: impl FnOnce(&Input) -> (Output, R)
) -> (CacheEntry<'k, Key, Scope, Input, Output, H>, R)[src]

Prepare the cache miss to be populated by running query(arg), returning a separate value. The value returned (R) is typically derived in some way from the stored Output.
