index

Indexing traits for indexing operations on collections. This module provides traits for implementing the indexing operator [], offering two distinct approaches to access elements in collections: * IndexView - For snapshot-based access * Index - For reference-based access # When to use which trait - Use IndexView when the collection can be accessed in a read-only context and is not mutated by a read access. This is the most common case in Cairo. - Use Index when the input type needs to be passed as ref. This is mainly useful for types depending on a Felt252Dict, where dictionary accesses are modifying the data structure itself. Only one of these traits should be implemented for any given type, not both. Felt252Dict: core::dict::Felt252Dict
