Trait FallibleIterator 

pub trait FallibleIterator {
    type Item;
    type Error: Error;

    // Required method
    fn next(&mut self) -> Result<Option<Self::Item>, Self::Error>;

    // Provided method
    fn collect<B>(self) -> Result<B, Self::Error>
       where B: FromIterator<Self::Item>,
             Self: Sized { ... }
}

Variation of the Iterator trait where each read can fail.

Required Associated Types

type Item

Type of items returned by this iterator.

type Error: Error

Type of errors that can occur when reading from this iterator.

Required Methods

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

Advances the iterator and returns the next value.

Errors

May fail depending on the implementation.

Provided Methods

fn collect<B>(self) -> Result<B, Self::Error>

where B: FromIterator<Self::Item>, Self: Sized,

Transforms an iterator into a collection.

Errors

This consumes the iterator and reads from it. If any read fails, the result is the first error encountered.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
