Enum HasMore

pub enum HasMore {
    Yes(usize),
    Maybe,
    No,
}

Returns whether or not the concurrent iterator has more elements to yield. Response is guaranteed to be true.

• Yes(n): the iterator will certainly yield n more elements.
• Maybe: the iterator might or might not yield any more element. A concurrent iterator created from an iterator with a non-trivial filter could be considered as an example. There certainly exists elements to evaluate, but not guaranteed to return one.
• No: the iterator has terminated, and will certainly not yield any more elements.

Variants

Yes(usize)

The iterator will certainly yield n more elements.

Maybe

The iterator might or might not yield any more element. A concurrent iterator created from an iterator with a non-trivial filter could be considered as an example. There certainly exists elements to evaluate, but not guaranteed to return one.

No

The iterator has terminated, and will certainly not yield any more elements.

Trait Implementations

impl Clone for HasMore

fn clone(&self) -> HasMore

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for HasMore

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for HasMore

fn eq(&self, other: &HasMore) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
