Struct HasEntry

Source 
pub struct HasEntry<K, V> { /* private fields */ }
Expand description

Matches if the map-like collection contains the given key/value pair.

The Matcher tests for this by converting the map-like data structure into a key/value pair iterator.

The alternative would be to use the Index trait though experiments showed that this would not be composable with all_of! or any_of!.
