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

`fn init() -> Self`

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

Important traits for Box<R>

impl<R> Read for Box<R> where
    R: Read + ?Sized, impl<W> Write for Box<W> where
    W: Write + ?Sized, impl<I> Iterator for Box<I> where
    I: Iterator + ?Sized,     type Item = <I as Iterator>::Item;

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

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