Trait failure_ext::StreamFailureExt

pub trait StreamFailureExt: Stream + Sized {
    pub fn context<D>(self, context: D) -> ContextStream<Self, D>
    where
        D: Display + Clone + Send + Sync + 'static;
    pub fn with_context<D, F>(self, f: F) -> WithContextStream<Self, F>

}

"Context" support for streams where the error is an implementation of std::error::Error.

    D: Display + Clone + Send + Sync + 'static,

pub fn with_context<D, F>(self, f: F) -> WithContextStream<Self, F> where
    D: Display + Clone + Send + Sync + 'static,
    F: FnMut() -> D, 

Add context created by provided function to the error returned by this stream
