Struct Indices 

pub struct Indices {
    pub start: isize,
    pub stop: isize,
    pub step: isize,
    pub len: usize,
}

A slice resolved against the length of a particular sequence.

Signed, because a slice walking backwards stops just before the front of the sequence and there is no unsigned way to say that.

Fields

start: isize

The first offset, which is not visited when Indices::len is zero.

stop: isize

One past the last offset, in the direction of travel.

step: isize

How far to move each time. Never zero, negative when walking backwards.

len: usize

How many elements this selects, which is the length of the result.

Implementations

impl Indices

pub fn offsets(self) -> impl Iterator<Item = usize>

The offsets this selects, in order.

pub const fn is_contiguous(self) -> bool

Whether this is a plain a:b with no step, which is the case a sequence can serve as one contiguous run.

Trait Implementations
