Struct a_range::Range

pub struct Range<Idx, Direction> { /* fields omitted */ }

A range

This is basically a start, and end, an a direction.

The index type can be any type, but to get a useful range, you need to supply something that implements some common traits, like Clone, and PartialEq; but also One (the identity element used) as well as AddAssign and SubAssign (to work increment/decrement the index).

Methods

impl<Idx> Range<Idx, Upwards> where     Idx: Clone + PartialEq + One + AddAssign + SubAssign,

Range counting up

pub fn collect<B>(self) -> B where     B: FromIterator<Idx>,

Collect range into a container

Works for any container type that implements FromIterator.

pub fn to_vec(&self) -> Vec<Idx>

Turn range into a Vec

impl<Idx> Range<Idx, Downwards> where     Idx: Clone + PartialEq + One + AddAssign + SubAssign,

Range counting down

pub fn collect<B>(self) -> B where     B: FromIterator<Idx>,

Collect range into a container

Works for any container type that implements FromIterator.

pub fn to_vec(&self) -> Vec<Idx>

Turn range into a Vec

Trait Implementations
