[−][src]Module lang_c::visit
Recursive abstract syntax tree traversal
struct ExprCount(usize); impl<'ast> visit::Visit<'ast> for ExprCount { fn visit_expression(&mut self, expr: &'ast ast::Expression, span: &'ast span::Span) { self.0 += 1; visit::visit_expression(self, expr, span); } }
The Visit trait is a collection of hooks, one for each type of node in the AST (for each type
in the ast module). Default implementations will recursively visit the sub-nodes (by calling
a corresponding free function in this module).
Free functions apply the visitor to sub-nodes of any given AST node.
