Rust Build Status Crates.io Docs.rs

Layered configuration system for Rust applications (with strong support for 12-factor applications).

  • Set defaults
  • Set explicit values (to programmatically override)
  • Read from JSON, TOML, YAML, HJSON, INI files
  • Read from environment
  • Loosely typed — Configuration values may be read in any supported type, as long as there exists a reasonable conversion
  • Access nested fields using a formatted path — Uses a subset of JSONPath; currently supports the child ( redis.port ) and subscript operators ( databases[0].name )
