Constant syntax::ast::DUMMY_NODE_ID [−] [src]

pub const DUMMY_NODE_ID: NodeId = NodeId(!0)

🔬 This is a nightly-only experimental API. (rustc_private)

this crate is being loaded from the sysroot, an unstable location; did you mean to load this crate from crates.io via Cargo.toml instead?

When parsing and doing expansions, we initially give all AST nodes this AST node value. Then later, in the renumber pass, we renumber them to have small, positive ids.
