Structs

NodeId

Identifies an AST node.

Constants

CRATE_NODE_ID

The NodeId used to represent the root of the crate.

DUMMY_NODE_ID

When parsing and at the beginning of doing expansions, we initially give all AST nodes this dummy AST NodeId. Then, during a later phase of expansion, we renumber them to have small, positive IDs.
