Partial Config

This is a WIP crate for providing a generic interface to configure one's application.

It is typical to see a configuration be composed from multiple sources: the command line, the environment variables, a config file, sometimes even through a web server.

This crate provides a generic way to do so.

Specifically, it provides

• Two traits Partial and Source
• A derive macro Partial that generates a new structure
• An implementation for Source if your configuration also is serde::de::DeserializeOwned
• Logic to combine multiple configuration sources
• Derive macro to produce detailed error reports
• Support for logging overlapping or overriding specifications
