serde-keyvalue-prim

A lightweight serde deserializer for strings containing key-value pairs separated by commas, as commonly found in command-line parameters or colon and semicolons as in simple line-based communication protocols.

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

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

or you need to parse a configuration string like:

type:bar;active:99;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.

The deserializer supports parsing signed and unsigned integers, booleans, strings (quoted or not), paths, and enums inside a top-level struct. The order in which the fields appear in the string is not important.
