Crate config

Config organizes hierarchical or layered configurations for Rust applications.

Config lets you set a set of default parameters and then extend them via merging in configuration from a variety of sources:

• Environment variables
• Another Config instance
• Remote configuration: etcd, Consul
• Files: JSON, YAML, TOML, HJSON
• Manual, programmatic override (via a .set method on the Config instance)

Additionally, Config supports:

• Live watching and re-reading of configuration files
• Deep access into the merged configuration via a path syntax
• Deserialization via serde of the configuration or any subset defined via a path

See the examples for general usage information.
