Struct process_results::Fallible

pub struct Fallible<I, C> { /* fields omitted */ }

Implementations

impl<I, C> Fallible<I, C> where
    I: IterResult,
    C: ErrorCollector<I::Error>, 

pub fn process<F, B>(self, f: F) -> Result<B, C::Collection> where
    F: FnOnce(RawIter<'_, I, C>) -> B, 

“Lift” a function of the values of an iterator so that it can process an iterator of Result values instead.

f is a closure that takes RawIter, an iterator adapter that wraps the inner iterator and implements Iterator<Item=I::OK>.

Returns either the returned value of closure f wrapped in the Ok variant, or the error wrapped in Err variant, in a way specified by C’s implementation of ErrorCollector.

pub fn process_no_discard<F, B>(self, f: F) -> (B, Option<C::Collection>) where
    F: FnOnce(RawIter<'_, I, C>) -> B, 

“Lift” a function of the values of an iterator so that it can process an iterator of Result values instead.

f is a closure that takes RawIter, an iterator adapter that wraps the inner iterator and implements Iterator<Item=I::OK>.

Returns both the returned value of closure f and None if the wrapped iterator runs to completion; otherwise, returns the intermediate value produced so far and the errors in a way specified by C’s implementation of ErrorCollector
