Trait configure::source::ConfigSource [−] [src]

pub trait ConfigSource: Send + Sync + 'static {
    fn init() -> Self;

    fn prepare(
        &self, 
        package: &'static str
    ) -> Box<DynamicDeserializer<'static>>;
}

A source for configuration.

If an end user wishes to pull configuration from the environment, they must specify their source, which is a type that implements ConfigSource. The source can be specified using the use_config_from! macro.

This crate ships a default source, called DefaultSource, which implements this trait.

Required Methods

Initialize this source. This will be called once when the program begins and then never called again.

Prepare a deserializer for a particular package. This will be called every time we generate configuration for that package.
