Expand description

Represent a GLSLT transform unit

The entry point of transform units is the parse_external_declaration, which processes its input syntax as GLSLT and updates the internal state of the transform unit accordingly. The other methods are for internal operation.

Required Methods§

source

fn global_scope(&self) -> &GlobalScope

Obtain a reference to the template definition context

source

fn global_scope_mut(&mut self) -> &mut GlobalScope

Obtain a mutable reference to the template definition context

source

fn push_function_declaration(&mut self, def: FunctionDefinition)

Add a function declaration to the transform unit

§Parameters
  • def: syntax tree for the function definition
source

fn parse_external_declaration( &mut self, extdecl: ExternalDeclaration, ) -> Result<Option<FnHandle<'_>>>

Parse a GLSLT declaration and add it to the transform unit

§Parameters
  • extdecl: top-level declaration to parse as GLSLT
