Struct egui::Vec2 [−]
A vector has a direction and length.
A Vec2
is often used to represent a size.
emath represents positions using Pos2
.
Normally the units are points (logical pixels).
Fields
x: f32
y: f32
Implementations
impl Vec2
pub const X: Vec2
pub const Y: Vec2
pub const ZERO: Vec2
pub const INFINITY: Vec2
pub fn zero() -> Vec2
Use Vec2::ZERO instead
pub fn infinity() -> Vec2
Use Vec2::INFINITY instead
pub const fn new(x: f32, y: f32) -> Vec2
pub const fn splat(v: f32) -> Vec2
Set both x
and y
to the same value.
#[must_use]pub fn normalized(self) -> Vec2
pub fn rot90(self) -> Vec2
Rotates the vector by 90°, i.e positive X to positive Y (clockwise in egui coordinates).
pub fn length(self) -> f32
pub fn length_sq(self) -> f32
pub fn angled(angle: f32) -> Vec2
Create a unit vector with the given angle (in radians).
- An angle of zero gives the unit X axis.
- An angle of 𝞃/4 = 90° gives the unit Y axis.
#[must_use]pub fn floor(self) -> Vec2
#[must_use]pub fn round(self) -> Vec2
#[must_use]pub fn ceil(self) -> Vec2
pub fn is_finite(self) -> bool
True if all members are also finite.
#[must_use]pub fn min(self, other: Vec2) -> Vec2
#[must_use]pub fn max(self, other: Vec2) -> Vec2
#[must_use]pub fn min_elem(self) -> f32
Returns the minimum of self.x
and self.y
.
#[must_use]pub fn max_elem(self) -> f32
Returns the maximum of self.x
and self.y
.
#[must_use]pub fn clamp(self, range: RangeInclusive<Vec2>) -> Vec2
