Extension trait for pahs’ Progress type for integration with snafu.

Required methods

fn snafu<C, F, E2>(self, context_fn: F) -> Progress<P, T, E2> where
    P: Clone,
    C: IntoError<E2, Source = E>,
    F: FnOnce(P) -> C,
    E2: Error + ErrorCompat, [src]

Maps the error of the progress to a snafu error, with the previous error as the source.

context_fn has to be a function that returns the context selector of that error.

fn into_snafu_leaf<C, F, E2>(self, context_fn: F) -> Progress<P, T, E2> where
    P: Clone,
    C: IntoError<E2, Source = NoneError>,
    F: FnOnce(E, P) -> C,
    E2: Error + ErrorCompat, [src]

Maps the error of the progress to a snafu leaf error.

context_fn has to be a function that returns the context selector of that leaf error.

fn snafu_leaf<C, F, E2>(self, context_fn: F) -> Progress<P, T, E2> where
    P: Clone,
    C: IntoError<E2, Source = NoneError>,
    F: FnOnce(P) -> C,
    E2: Error + ErrorCompat, [src]

Replaces the error of the progress with a snafu leaf error.

context_fn has to be a function that returns the context selector of that leaf error.

If you get an error because E cannot be inferred, try using into_snafu_leaf instead to specify the type of the error (first context_fn parameter).
