Fields

version: GLSLVersion

Target GLSL version.

stage: GLSLShaderStage

Pipeline stage.

extensions: Vec<String>

Extension enable directives (e.g. "GL_ARB_shader_storage_buffer_object").

defines: Vec<(String, Option<String>)>

Global #define macros (name, optional value).

structs: Vec<GLSLStruct>

Struct type definitions (emitted before globals).

inputs: Vec<GLSLVariable>

Global in variables (stage inputs).

outputs: Vec<GLSLVariable>

Global out variables (stage outputs).

uniforms: Vec<GLSLVariable>

Global uniform variables.

globals: Vec<GLSLVariable>

Additional global variables (e.g. shared memory in compute).

functions: Vec<GLSLFunction>

Helper functions (emitted before main).

main_body: Vec<String>

Body statements of the implicit void main() function.
