Struct QuadData

#[repr(C)]
pub struct QuadData {
    pub color: [f32; 4],
    pub src_rect: [f32; 4],
    pub dst_rect: [f32; 4],
    pub offset: [f32; 2],
    pub rotation: f32,
}

Data we need for each quad instance. DrawParam gets turned into this, eventually. We have to be quite particular about layout since this gets fed straight to the shader.

Fields

color: [f32; 4]

Color to blend the result texture with.

src_rect: [f32; 4]

Source region on the texture to draw, coordinates range from 0 to 1

dst_rect: [f32; 4]

Destination rectangle in your render target to draw the texture on, coordinates are whatever you set in your transform and viewport.

offset: [f32; 2]

Rotation offset – A point within your dst_rect to rotate around, coordinates range from 0 to 1

rotation: f32

Rotation, in radians, CCW.

Implementations

impl QuadData

pub const fn empty() -> Self

Returns an empty QuadData with default values.

Trait Implementations

impl Clone for QuadData

fn clone(&self) -> QuadData

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for QuadData

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

Formats the value using the given formatter.

impl PartialEq for QuadData

fn eq(&self, other: &QuadData) -> 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 PartialOrd for QuadData

fn partial_cmp(&self, other: &QuadData) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl Zeroable for QuadData

fn zeroed() -> Self

Calls zeroed.

impl Copy for QuadData

impl Pod for QuadData

impl StructuralPartialEq for QuadData
