Function brane_ast::traversals::flatten::do_traversal

pub fn do_traversal(
    state: &mut CompileState,
    root: Program,
) -> Result<Program, Vec<AstError>>

Flattens the symbol tables in the given AST to only have a global and function-wide scope.

Note that this cannot lead to conflicts, since variable names (should) have already been resolved.

Arguments

• state: The CompileState that we use to pre-define and flatten scopes in.
• 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 a flattened symbol table structure (i.e., nested blocks will have empty tables).

Errors

This pass doesn’t really error, but the option is here for convention purposes.
