pub fn add_source<S, E>(self, source: S) -> Self

where E: Error + 'static, S: Source<Error = E> + 'static,

where E: Error + 'static, S: Source<Error = E> + 'static, K: AsRef<Key>,

Adds a new Source such that the sources provided keys are available from the supplied prefix.

Note: The order that sources are added, are the order that they are checked for values, so you want to add your source with the highest priority first.
