High-level shader description that gets compiled to TGSI instructions.

Variants

SetColor

Set output colour to a constant.

Fields

r: u8

g: u8

b: u8

a: u8

TintByUniform

Multiply output by a uniform colour.

Fields

uniform_name: String

SampleTexture

Sample a texture at the fragment coordinate.

Fields

sampler: u8

VerticalGradient

Apply a simple gradient (top-to-bottom).

Fields

top: u32

bottom: u32

Passthrough

Passthrough (identity — copy input to output).

Trait Implementations

impl Clone for ShaderOp

fn clone(&self) -> ShaderOp

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ShaderOp

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

Formats the value using the given formatter.

impl PartialEq for ShaderOp

fn eq(&self, other: &ShaderOp) -> 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.
