Struct jobsteal::iter::Hide
[−]
[src]
pub struct Hide<T>(_);
Used to mask data so that implementations don't conflict.
Specifically, this is used in the implementation of Spliterator
for Zip, by hiding the base. This is because Spliterator requires
that the base be Split. However, for Split types, there is a blanket
impl for Spliterator for convenience, so if we didn't mask the type,
there would be conflicting implementations of Spliterator for Zip.
This will be obsoleted when specialization becomes stable.
Numerous other iterator adapters also use this, but will all be cleared by specialization.
Trait Implementations

Which kind of iterator are we turning this into?
fn into_iter(self) -> Self::IntoIter
Creates an iterator from a value. Read more
