Struct emath::Pos2

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

y: f32

Implementations

impl Pos2

pub const fn 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

#[must_use]pub fn min(self, other: Self) -> Self

#[must_use]pub fn max(self, other: Self) -> Self

#[must_use]pub fn clamp(self, range: RangeInclusive<Self>) -> Self
