Container traits

Traits for container objects.

Standard containers (Vec, HashMap, HashSet, BTreeMap, ...) implements several strategies that make unfeasable to have a generic trait covering all these use cases. This crate then chooses to split it into several different subtraits that allows you to implement only those that are useful for you.

Optional features

• alloc: links the alloc crate and provide implementations for containers like Vec, BTreeMap, ...
• std: links the std crate and provides implementation for HashMap.
