Serde deserializer from key=value strings

A lightweight serde deserializer for strings containing key-value pairs separated by commas, as commonly found in command-line parameters.

Say your program takes a command-line option of the form:

--foo type=bar,active,nb_threads=8

This crate provides a from_key_values function that deserializes these key-values into a configuration structure. Since it uses serde, the same configuration structure can also be created from any other supported source (such as a TOML or YAML configuration file) that uses the same keys.

Integration with the argh command-line parser is also provided via the argh_derive feature.

See the inline documentation for examples and more details.
