Crate config

Expand description

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.
