Struct RangeIterRev

Source 
pub struct RangeIterRev<T> { /* private fields */ }
Expand description

Reversed const-iterator for Range

This is constructed like this:

konst::iter::into_iter!(0..10).rev()

Implementations§

Source§

impl<T> RangeIterRev<T>
where T: Step,

Source

pub const fn copy(&self) -> RangeIterRev<T>
