Pantry is useful for temporarily storing for later use values that
might "decay" (become unusable) over time.
Pantry value and use its
store function to store values
for later use. A key is provided along with the value, so that the value
can be retrieved later using the same key. A worker thread is spawned
which monitors the values and automatically drops any which have "decayed".
Values must implement the
Perishable trait, whose
asynchronously completes once the value has decayed.
fetch asynchronous function on the
Pantry with a key to
retrieve a value previously stored using that key. A value is only
returned if it was stored using the same key and has not decayed since it
Multiple values may have the same key, with the caveat that the values stored under a given key may not be returned in the same order in which they were stored.
Each value of this type maintains a collection of stored values that might
"decay" or become unusable over time. Values are added to the collection
This is the trait that values must implement in order to be stored in the
