Struct InstanceRect 

#[repr(C)]
pub struct InstanceRect {
    pub pos: [f32; 2],
    pub size: [f32; 2],
    pub color: [f32; 4],
    pub corner_radius: f32,
    pub _pad: [f32; 3],
}

Per-instance data for a single instanced rectangle.

36 bytes, #[repr(C)], Pod + Zeroable so it can be uploaded directly.

Fields

pos: [f32; 2]

Top-left corner in pixel space.

size: [f32; 2]

Width × height in pixels.

color: [f32; 4]

Straight-alpha RGBA colour in [0, 1].

corner_radius: f32

Uniform corner radius in pixels (0 = sharp).

_pad: [f32; 3]

Padding to align to 4 bytes.

Implementations

impl InstanceRect

pub fn rect(pos: [f32; 2], size: [f32; 2], color: [f32; 4]) -> Self

Construct an instance with no corner radius.

pub fn rounded( pos: [f32; 2], size: [f32; 2], color: [f32; 4], corner_radius: f32, ) -> Self

Construct an instance with a uniform corner radius.

Trait Implementations

impl Clone for InstanceRect

fn clone(&self) -> InstanceRect

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for InstanceRect

impl Debug for InstanceRect

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

Formats the value using the given formatter.

impl PartialEq for InstanceRect

fn eq(&self, other: &InstanceRect) -> 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 Pod for InstanceRect

impl StructuralPartialEq for InstanceRect

impl Zeroable for InstanceRect

fn zeroed() -> Self

Calls zeroed.
