Module tari_common::configuration::loader

Application configuration

Tari is using config crate which allows to extend config file with application level configs. To allow deriving configuration from a Config via ConfigLoader trait application configuration struct should implements Deserialize and NetworkConfigPath traits.

ConfigLoader::load_from logic will include automated overloading of parameters from [application.{network}] subsection, where network is specified in application.network parameter.

ConfigPath allows to customize overloading logic event further and DefaultConfigLoader trait accounts for struct Defaults when loading values.

Example

#[derive(Deserialize)]
struct MyNodeConfig {
    welcome_message: String,
}
impl NetworkConfigPath for MyNodeConfig {
    fn main_key_prefix() -> &'static str {
        "my_node"
    }
}

config.set("my_node.network", "rincewind");
config.set("my_node.rincewind.welcome_message", "nice to see you at unseen");
let my_config = <MyNodeConfig as ConfigLoader>::load_from(&config).unwrap();
assert_eq!(my_config.welcome_message, "nice to see you at unseen");
