Trait Source 

pub trait Source<C: HasPartial> {
    type Error: Debug;

    // Required methods
    fn to_partial(self) -> Result<C::Partial, Self::Error>;
    fn name(&self) -> String;
}

The implementor of this trait is a source of configuration. The method Source::to_partial obtains a single layer of configuration and from a given source.

This trait is mostly used for trait-level type checking so that the Partial::source method operates as expected. No user is ever expected to call Source::to_partial directly.

Required Associated Types

type Error: Debug

Required Methods

fn to_partial(self) -> Result<C::Partial, Self::Error>

Obtain a partial layer from Self. Not user facing, but used inside the Partial::source for type checking.

fn name(&self) -> String

The name that is being printed whenever this layer of configuration is being parsed. If you came across this method to silence the Sourcing configuration from XXX message, instead simply override the Partial::source method instead.
