config-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 )
