pub struct GenericSubstitution(pub OrderedHashMap<GenericParamId, GenericArgumentId>);
Expand description

A substitution of generic arguments in generic parameters. Used for concretization.

§0: OrderedHashMap<GenericParamId, GenericArgumentId>

Methods from Deref<Target = OrderedHashMap<GenericParamId, GenericArgumentId>>§

Returns a reference to the value stored for key, if it is present, else None.

Computes in O(1) time (average).

Returns an iterator over the key-value pairs of the map, in their order.

Returns an iterator over the keys of the map, in their order.

Returns an iterator over the values of the map, in their order.

Returns true if an equivalent to key exists in the map.

Returns the number of key-value pairs in the map.

Returns true if the map contains no elements.

Trait Implementations§

Returns a copy of the value. Read more
Performs copy-assignment from source. Read more
Formats the value using the given formatter. Read more
Returns the “default value” for a type. Read more
The resulting type after dereferencing.
Dereferences the value.
Feeds this value into the given Hasher. Read more
Feeds a slice of this type into the given Hasher. Read more
This method tests for self and other values to be equal, and is used by ==.
This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
