Struct std::iter::FuseStable

#[must_use = "iterator adaptors are lazy and do nothing unless consumed"]
pub struct Fuse<I> {
    // some fields omitted
}

An iterator that yields None forever after the underlying iterator yields None once.

Methods

impl<I> Fuse<I>

fn reset_fuse(&mut self)

Resets the fuse such that the next call to .next() or .next_back() will call the underlying iterator again even if it previously returned None.
