Struct naga::front::wgsl::index::Index

pub struct Index<'a> {
    dependency_order: Vec<Handle<GlobalDecl<'a>>>,
}

A GlobalDecl list in which each definition occurs before all its uses.

Fields

dependency_order: Vec<Handle<GlobalDecl<'a>>>

Implementations

impl<'a> Index<'a>

pub fn generate(tu: &TranslationUnit<'a>) -> Result<Self, Error<'a>>

Generate an Index for the given translation unit.

Perform a topological sort on tu’s global declarations, placing referents before the definitions that refer to them.

Return an error if the graph of references between declarations contains any cycles.

pub fn visit_ordered(&self) -> impl Iterator<Item = Handle<GlobalDecl<'a>>> + '_

Iterate over GlobalDecls, visiting each definition before all its uses.

Produce handles for all of the GlobalDecls of the TranslationUnit passed to Index::generate, ordered so that a given declaration is produced before any other declaration that uses it.
