Struct array_map::ArrayMap [−][src]
pub struct ArrayMap<K, V, const N: usize> { /* fields omitted */ }
Expand description
A Map backed by an array. The keys must be known statically.
This map is O(1) for all operations. All members must be initialized at creation time so there is no option to insert or remove items from the map. Because of this it can be indexed into using the key type.
Implementations
Returns a new ArrayMap
where all the values are initialized to the same value
Returns a new ArrayMap
where all the values are initialized to the value returned from each call of the closure.
Panics
Panics if K::iter()
returns anything other than N
items or if K::index()
returns a value >= N
Returns a new ArrayMap
where all the values are initialized to the same value
Errors
Returns an error the first time that the provided closure returns an error.
Panics
Panics if K::iter()
returns anything other than N
items or if K::index()
returns a value >= N
Collects an iterator of (K, Result<V, E>)
into a Result<Self, E>
The trait FromIterator
cannot be implemented for Result
like it is on a Vec because of the orphan rules.
Errors
Returns an error with the first emitted error from the provided iterator
Panics
Panics if any of the safety requirements in the Indexable
trait are wrong
