# Struct im::ordmap::OrdMap
[−]
[src]

pub struct OrdMap<K, V>(_);

# Ordered Map

An immutable ordered map implemented as a B-tree.

Most operations on this type of map are O(log n). A
`HashMap`

is usually a better choice for
performance, but the `OrdMap`

has the advantage of only requiring
an `Ord`

constraint on the key, and of being
ordered, so that keys always come out from lowest to highest,
where a `HashMap`

has no guaranteed ordering.

F: Fn(Arc<V>) -> Option<Arc<V>>,

[src]

This is like the `update`

method, except with more
control: the function gets an
`Option<V>`

and returns the same, so
that it can decide to delete a mapping instead of updating the
value, and decide what to do if the key isn't in the map.

Time: O(log n)
