okcodes-config

Just a clone of config created to test opened and non-merged PRs on that project. This crate is unstable since early features will be tested here, the original config crate should be used.

lib.rs:

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
• String literals in well-known formats
• Another Config instance
• Files: TOML, JSON, YAML, INI, RON, JSON5 and custom ones defined with Format trait
• 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.
