Crate confu[−][src]
Expand description
Confu is a no frills Rust application configuration library. It supports getting configuration from environment, command line arguments and defaults.
Specificity: defaults -> environment -> arguments. Arguments being the most specific, will take precedence over the corresponding environment values, or default values, if such were also defined.
Examples

use confu::Confu; #[derive(Confu)] #[confu_prefix = "APP_"] struct Config { #[default = "postgres"] db_user: String, #[protect] #[default = "postgres"] db_password: String, #[default = "127.0.0.1"] api_host: String, #[require] telemetry: String, #[hide] super_secret_stuff: String, } fn main() { let config = Config::confu(); config.show(); }
