Struct GradientDescriptor 

pub struct GradientDescriptor {
    pub gradient_type: u32,
    pub start: Vec2,
    pub end: Vec2,
    pub radius: f32,
    pub color_start: Vec4,
    pub color_end: Vec4,
}

Describes a gradient fill for a UI element.

Stored on the GPU slab.

Fields

gradient_type: u32

The type of gradient (None, Linear, Radial).

start: Vec2

For linear: start point (in element-local 0..1 space). For radial: center point.

end: Vec2

For linear: end point. For radial: unused.

radius: f32

For radial: the radius. For linear: unused.

color_start: Vec4

Color at the start (or center for radial).

color_end: Vec4

Color at the end (or edge for radial).

Trait Implementations

impl Clone for GradientDescriptor

fn clone(&self) -> GradientDescriptor

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for GradientDescriptor

impl Debug for GradientDescriptor

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

Formats the value using the given formatter.

impl Default for GradientDescriptor

fn default() -> GradientDescriptor

Returns the “default value” for a type.

impl PartialEq for GradientDescriptor

fn eq(&self, other: &GradientDescriptor) -> 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 SlabItem for GradientDescriptor

where u32: SlabItem, Vec2: SlabItem, f32: SlabItem, Vec4: SlabItem,

const SLAB_SIZE: usize

The number of u32s this type occupies in a slab of &[u32].

fn read_slab(index: usize, slab: &[u32]) -> Self

Read the type out of the slab at index.

fn write_slab(&self, index: usize, slab: &mut [u32]) -> usize

Write the type into the slab at starting index and return the new index.
