Struct Offset

Source
pub struct Offset(pub i32, pub i32);
Expand description

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.

This may be converted to Size with from / into.

Implementations§

Source§

impl Offset

Source

pub const ZERO: Self

The constant (0, 0)

Source

pub const MIN: Self

The minimum value

Source

pub const MAX: Self

The maximum value

Source

pub fn lt(self, rhs: Self) -> bool

True when for all components, lhs < rhs

Source

pub fn le(self, rhs: Self) -> bool

True when for all components, lhs ≤ rhs

Source

pub fn ge(self, rhs: Self) -> bool

True when for all components, lhs ≥ rhs

Source

pub fn gt(self, rhs: Self) -> bool

True when for all components, lhs > rhs

Source

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

Return the minimum, componentwise

Source

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

Return the maximum, componentwise

Source

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

Restrict a value to the specified interval, componentwise

Source

pub fn transpose(self) -> Self

Return the transpose (swap x and y values)

Source

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

Return the result of component-wise multiplication

Source

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

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

Source

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 fn new(x: i32, y: i32) -> Self

Construct

Source

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

Construct, using the same value on all axes
