total-maps

Maps where every possible key has an associated value.

Only entries with uncommon values are actually stored in the map; all other keys are presumed to be associated with a common value. The definition of "common" and "uncommon" can be customized via the Commonality trait.

Cargo features

• num-traits: provides a commonality implemented in terms of num_traits::Zero.

lib.rs:

Maps where every possible key has an associated value.

Only entries with uncommon values are actually stored in the map; all other keys are presumed to be associated with a common value. The definition of "common" and "uncommon" is determined by the map's optional [Commonality] type parameter; if unspecified, the map will use [DefaultCommonality], which uses the standard [Default] trait to provide the common value.

[TotalHashMap] is the main data structure provided by this crate.
