[src]
pub struct Map<'ast> {
// some fields omitted
}Represents a mapping from Node IDs to AST elements and their parent Node IDs
Methods
impl<'ast> Map<'ast>
fn krate(&self) -> &'ast Crate
fn get(&self, id: NodeId) -> Node<'ast>
Retrieve the Node corresponding to id, panicking if it cannot
be found.
fn find(&self, id: NodeId) -> Option<Node<'ast>>
Retrieve the Node corresponding to id, returning None if
cannot be found.
fn get_parent(&self, id: NodeId) -> NodeId
Retrieve the parent NodeId for id, or id itself if no
parent is registered in this map.
fn get_parent_did(&self, id: NodeId) -> DefId
fn get_foreign_abi(&self, id: NodeId) -> Abi
fn get_foreign_vis(&self, id: NodeId) -> Visibility
fn expect_item(&self, id: NodeId) -> &'ast Item
fn expect_struct(&self, id: NodeId) -> &'ast StructDef
fn expect_variant(&self, id: NodeId) -> &'ast Variant
fn expect_foreign_item(&self, id: NodeId) -> &'ast ForeignItem
fn expect_expr(&self, id: NodeId) -> &'ast Expr
fn get_path_elem(&self, id: NodeId) -> PathElem
returns the name associated with the given NodeId's AST
fn with_path<T, F>(&self, id: NodeId, f: F) -> T where F: FnOnce(PathElems) -> T
fn path_to_string(&self, id: NodeId) -> String
fn with_attrs<T, F>(&self, id: NodeId, f: F) -> T where F: FnOnce(Option<&[Attribute]>) -> T
Given a node ID and a closure, apply the closure to the array of attributes associated with the AST corresponding to the Node ID
fn nodes_matching_suffix<'a>(&'a self, parts: &'a [String]) -> NodesMatchingSuffix<'a, 'ast>
Returns an iterator that yields the node id's with paths that
match parts. (Requires parts is non-empty.)
For example, if given parts equal to ["bar", "quux"], then
the iterator will produce node id's for items with paths
such as foo::bar::quux, bar::quux, other::bar::quux, and
any other such items it can find in the map.
