Struct grr::Shader

#[repr(transparent)]
pub struct Shader(_);

Shader.

Shaders are programmable parts of Pipelines. Each shader has a fixed ShaderStage in the pipeline. Shaders may be reused in different pipelines and specify the operations which will transform a predefined set of inputs into a set of output variables. The shader stages defines the input and output layout.

Beside the input and output variables, shaders can also access GPU memory via bound buffers and images.

Shading Lanuage

OpenGL comes with an defined Shading Language (GLSL), which will be also used in the documentation for writing shaders. The OpenGL drivers will translate the GLSL shaders into IHV specific machine language via an built-in compiler. Beside the shader representation in text form (GLSL) with GL 4.6 comes also support for the binary SPIR-V format.
