Function brane_ast::traversals::resolve::do_traversal

source · 
pub fn do_traversal(
    state: &mut CompileState,
    package_index: &PackageIndex,
    data_index: &DataIndex,
    root: Program,
) -> Result<Program, Vec<AstError>>
Expand description

Builds symbol tables for the given brane-dsl AST.

This effectively resolves variable references.

§Arguments

  • state: The CompileState that we can use to remember definitions in between runs.
  • package_index: The PackageIndex which we use to resolve external function calls.
  • data_index: The DataIndex which we use to resolve external data assets.
  • root: The root node of the tree on which this compiler pass will be done.

§Returns

The same nodes as went in, but now with non-empty symbol tables.

§Errors

TThis pass may throw AstError::ResolveErrors if the user made mistakes with their variable references.
