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

Extend the map with all key-value pairs in the iterable.

This is equivalent to calling insert for each of them in order, which means that for keys that already existed in the map, their value is updated but it keeps the existing order.

New keys are inserted in the order they appear in the sequence. If equivalents of a key occur more than once, the last corresponding value prevails.

🔬This is a nightly-only experimental API. (extend_one)

Extends a collection with exactly one element.

Reserves capacity in a collection for the given number of additional elements. Read more

Converts to this type from the input type.

Creates a value from an iterator. Read more

Create an OrderMap from the sequence of key-value pairs in the iterable.

from_iter uses the same logic as extend. See extend for more details.

This method tests for self and other values to be equal, and is used by ==. Read more

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason. Read more
