Struct Offset 

pub struct Offset(pub i32, pub i32);

A (x, y) offset, also known as a vector

This is a relative position. It can be added to or subtracted from a Coord, and it can be added to or subtracted from itself. It can be negative. It can be multiplied by a scalar.

Offset implements PartialOrd such that the comparison must be true of all components: for example a < b == a.0 < b.0 && a.1 < b.1. If c == Offset(0, 1) and d == Offset(1, 0) then c != d && !(c < d) && !(c > d). Offset does not implement Ord.

This may be converted to Size with from / into.

Implementations

impl Offset

pub const ZERO: Self

The constant (0, 0)

pub const MIN: Self

The minimum value

pub const MAX: Self

The maximum value

pub fn min(self, other: Self) -> Self

Return the minimum, componentwise

pub fn max(self, other: Self) -> Self

Return the maximum, componentwise

pub fn clamp(self, min: Self, max: Self) -> Self

Return the transpose (swap x and y values)

pub fn cwise_mul(self, rhs: Self) -> Self

Return the result of component-wise multiplication

pub fn cwise_div(self, rhs: Self) -> Self

pub fn extract<D: Directional>(self, dir: D) -> i32

This merely extracts the horizontal or vertical component. It never negates it, even if the axis is reversed.

pub fn set_component<D: Directional>(&mut self, dir: D, value: i32)

Set one component of self, based on a direction

This does not negate components when the direction is reversed.

pub const fn splat(n: i32) -> Self

Construct, using the same value on all axes
