Struct emath::RectTransform

#[repr(C)]
pub struct RectTransform {
    from: Rect,
    to: Rect,
}

Linearly transforms positions from one Rect to another.

RectTransform stores the rectangles, and therefore supports clamping and culling.

Fields

from: Rect

to: Rect

Implementations

impl RectTransform

pub fn identity(from_and_to: Rect) -> Self

pub fn from_to(from: Rect, to: Rect) -> Self

pub fn from(&self) -> &Rect

pub fn to(&self) -> &Rect

pub fn scale(&self) -> Vec2

The scale factors.

pub fn inverse(&self) -> Self

pub fn transform_pos(&self, pos: Pos2) -> Pos2

Transforms the given coordinate in the from space to the to space.

pub fn transform_rect(&self, rect: Rect) -> Rect

Transforms the given rectangle in the in-space to a rectangle in the out-space.

pub fn transform_pos_clamped(&self, pos: Pos2) -> Pos2

Transforms the given coordinate in the from space to the to space, clamping if necessary.

Trait Implementations

impl Clone for RectTransform

fn clone(&self) -> RectTransform

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for RectTransform

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Mul<Pos2> for &RectTransform

Transforms the position.

type Output = Pos2

The resulting type after applying the * operator.

fn mul(self, pos: Pos2) -> Pos2

Performs the * operation.

impl Mul<Pos2> for RectTransform

Transforms the position.

type Output = Pos2

The resulting type after applying the * operator.

fn mul(self, pos: Pos2) -> Pos2

Performs the * operation.

impl PartialEq for RectTransform

fn eq(&self, other: &RectTransform) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Zeroable for RectTransform

fn zeroed() -> Self

Calls zeroed.
