Enum ColorParam

pub enum ColorParam {
    Color(Box<[f32; 4]>),
    Param(Box<str>),
    Texture(Box<Texture>),
}

A type that describes color attributes of fixed-function shader elements inside ProfileCommon effects.

Variants

Color(Box<[f32; 4]>)

The value is a literal color, specified by four floating-point numbers in RGBA order.

Param(Box<str>)

The value is specified by a reference to a previously defined parameter in the current scope that can be cast directly to a float4.

Texture(Box<Texture>)

The value is specified by a reference to a previously defined sampler2D object.

Implementations

impl ColorParam

pub fn color(rgba: [f32; 4]) -> Self

Construct a new ColorParam from a color.

impl ColorParam

pub fn as_texture(&self) -> Option<&Texture>

Convert this parameter to a texture reference, if it is one.

pub fn as_color(&self) -> Option<&[f32; 4]>

Get the color literal of this parameter, if it is a literal.
