Trait Implementations

impl<'r, C, U, F, T> Folder<T> for TryFoldFolder<'r, C, U, F>

where C: Folder<U>, F: Fn(U::Output, T) -> U + Sync, U: Try,

type Result = <C as Folder<U>>::Result

The type of result that will ultimately be produced by the folder.

fn consume(self, item: T) -> Self

Consume next item and return new sequential state.

fn complete(self) -> C::Result

Finish consuming items, produce final result.

fn full(&self) -> bool

Hint whether this Folder would like to stop processing further items, e.g. if a search has been completed.

fn consume_iter<I>(self, iter: I) -> Self

where I: IntoIterator<Item = Item>,

Consume items from the iterator until full, and return new sequential state.
