Trait shaku::Provider

pub trait Provider<M: Module>: 'static {
    type Interface: ?Sized;
    fn provide(module: &M) -> Result<Box<Self::Interface>, Box<dyn Error>>;
}

Like Components, providers provide a service by implementing an interface.

Unlike Component, Provider represents a temporary service. Examples include a connection to a remote service or pooled database connection. Because only providers can have other providers as dependencies, services which use these provided services must also be Providers (ex. DB repository, service using a DB repository, etc).
