Trait failure_ext::FutureFailureErrorExt

pub trait FutureFailureErrorExt: Future + Sized {
    pub fn context<D>(self, context: D) -> ContextErrorFut<Self, D>
    where
        D: Display + Send + Sync + 'static;
    pub fn with_context<D, F>(self, f: F) -> WithContextErrorFut<Self, F>
    where
        D: Display + Send + Sync + 'static,
        F: FnOnce() -> D;
}

"Context" support for futures where the error is anyhow::Error.

Required methods

pub fn context<D>(self, context: D) -> ContextErrorFut<Self, D> where
    D: Display + Send + Sync + 'static, 

Add context to the error returned by this future

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

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