Crate vecmap

vecmap-rs

A vector-based ordered map implementation with zero dependencies and support for #![no_std].

Map keys are not required to be hashable and do not need to form a total order. Therefore, VecMap<K, V> can be used with key types which neither implement Hash nor Ord.

Since vecmap-rs is a Vec<(K, V)> under the hood, worst case lookup and insertion performance is O(n) and scales with the number of map entries. Thus, its main use case are small collections with unhashable keys.

For key types that implement Hash and Ord consider using a map implementation with better performance such as HashMap and BTreeMap from the standard library or popular alternatives like IndexMap.

Cargo features

The following features are available:

• serde: Provides Serialize and Deserialize implementations for VecMap. This feature is disabled by default. Enabling it will pull in serde as a dependency.
