Enum glsl::syntax::Preprocessor

pub enum Preprocessor {
    Define(PreprocessorDefine),
    Version(PreprocessorVersion),
    Extension(PreprocessorExtension),
}

Some basic preprocessor commands.

As it’s important to carry them around the AST because they cannot be substituted in a normal preprocessor (they’re used by GPU’s compilers), those preprocessor commands are available for inspection.

Important note: so far, only #version and #extension are supported. Other pragmas will be added in the future. Stay tuned.

Variants

Define(PreprocessorDefine)

Version(PreprocessorVersion)

Extension(PreprocessorExtension)
