Struct emath::Pos2

#[repr(C)]
pub struct Pos2 {
    pub x: f32,
    pub y: f32,
}

A position on screen.

Normally given in points (logical pixels).

Mathematically this is known as a “point”, but the term position was chosen so not to conflict with the unit (one point = X physical pixels).

Fields

x: f32

How far to the right.

y: f32

How far down.

Implementations

impl Pos2

pub const ZERO: Self = _

The zero position, the origin. The top left corner in a GUI. Same as Pos2::default().

pub const fn new(x: f32, y: f32) -> Self

pub fn to_vec2(self) -> Vec2

The vector from origin to this position. p.to_vec2() is equivalent to p - Pos2::default().

pub fn distance(self, other: Self) -> f32

pub fn distance_sq(self, other: Self) -> f32

pub fn floor(self) -> Self

pub fn round(self) -> Self

pub fn ceil(self) -> Self

pub fn is_finite(self) -> bool

True if all members are also finite.

pub fn any_nan(self) -> bool

True if any member is NaN.

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

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

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

pub fn lerp(&self, other: Self, t: f32) -> Self

Linearly interpolate towards another point, so that 0.0 => self, 1.0 => other.
