mixins/reverse_indexable_container

module ReverseIndexableContainer

A mixin for containers that have are indexable using [] and []=. The container must have a method reverse_each_pair that iterates through the elements using index/value (or key/value).

Public Methods

rindex(value)

Find the key (or index) for a given value, searching backward through the container using reverse_each_pair

value	the value to search for

Returns: a key (or index) that matches the given value. If none is found, returns the default value (or if the container has no default value, returns nil). If there are multiple keys that match the value, then the result is indeterminate.
