Module differential_dataflow::collection::lookup
[−]
[src]
A trait for maps from K to V and implementations.
The Lookup<K,V> trait corresponds to a map from K to V. This can be
implemented many different ways based on different requirements. A HashMap<K,V>
is a general solution for K: Hash, whereas a Vec<(K,V)> is a primitive but
often effective solution for K: Eq, the minimal requirement.
Other implementations include a Vec<Option<V>> for usize keys, and a RHHMap
implementation based on a Robin Hood hashing implementation.
