Trait TryIntoNonEmptyIterator 

pub trait TryIntoNonEmptyIterator: Sealed {
    type Item;
    type IntoNonEmptyIter: NonEmptyIterator<Item = Self::Item>;

    // Required method
    fn try_into_non_empty_iter(self) -> Option<Self::IntoNonEmptyIter>;
}

Convenience trait implemented for any type that is IntoIterator, allowing to convert iterables into non-empty ones.

Required Associated Types

type Item

The type of the items being iterated over.

type IntoNonEmptyIter: NonEmptyIterator<Item = Self::Item>

Which kind of NonEmptyIterator are we turning this into?

Required Methods

fn try_into_non_empty_iter(self) -> Option<Self::IntoNonEmptyIter>

Tries to convert self into NonEmptyIterator.

Returns None if self is empty and therefore can not be converted.
