Struct AsyncValue 

Source 
pub struct AsyncValue<K, T, E>(/* private fields */);
Expand description

A declaration of one read. All changing request inputs belong in key. Loader execution is untracked and uses the supplied local executor. Reads participate when reached by a boundary, not merely when declared.
