Struct IterInput 

pub struct IterInput<I, C>
where
    I: Iterator,
{ /* private fields */ }

An input adapter that wraps any iterator and provides a TryNextWithContext interface, automatically fusing the iterator so it never yields items after returning None once.

Type Parameters

• I: The underlying iterator type. It can be any Iterator.
• C: The context type, which is passed by mutable reference to each try_next_with_context call.

Implementations

impl<I, C> IterInput<I, C>

where I: Iterator,

pub fn from(iter: I) -> Self

Creates a new IterInput from any iterator.

The iterator is automatically fused internally, so that once it returns None, all further next() calls will also return None.

Trait Implementations

impl<I, C> TryNextWithContext for IterInput<I, C>

where I: Iterator,

type Item = <I as Iterator>::Item

The type of items yielded by this source.

type Error = Infallible

The error type that may be returned when producing the next item fails.

type Context = C

The type of context passed to each call to try_next.

fn try_next_with_context( &mut self, _context: &mut Self::Context, ) -> Result<Option<Self::Item>, Self::Error>

Attempts to produce the next item, using the provided mutable context.

fn try_collect_with_context( &mut self, context: &mut Self::Context, ) -> Result<Vec<Self::Item>, Self::Error>

Collects all remaining items into a Vec, using the given context.
