ommui_string_patterns 0.1.2

This crate contains (de-)serialization modules that can be used for string items with serde. The (de-)serialization will fail if the required pattern is not matched. This behavior is achieved by matching against a regular expression which defines the allowed pattern.

The modules in this crate can be used by the with attribute of serde, attached to String elements.
