Trait fehler::Context

pub trait Context<T, E> {
    fn context<C: Display + Send + Sync + 'static>(
        self, 
        context: C
    ) -> Result<T, Exception>;
    fn with_context<C, F>(self, f: F) -> Result<T, Exception>
    where
        C: Display + Send + Sync + 'static,
        F: FnOnce(&E) -> C;
}

Provides the context method for Result.

fn context<C: Display + Send + Sync + 'static>(
    self,
    context: C
) -> Result<T, Exception>
