Trait sgx_tstd::iter::FusedIterator 1.26.0[−][src]
pub trait FusedIterator: Iterator { }
An iterator that always continues to yield None when exhausted.
Calling next on a fused iterator that has returned None once is guaranteed
to return None again. This trait should be implemented by all iterators
that behave this way because it allows for some significant optimizations.
Note: In general, you should not use FusedIterator in generic bounds if
you need a fused iterator. Instead, you should just call Iterator::fuse
on the iterator. If the iterator is already fused, the additional Fuse
wrapper will be a no-op with no performance penalty.
