Function syntax::ext::tt::macro_parser::get_macro_ident[][src]

fn get_macro_ident(token: &Token) -> Option<(Ident, bool)>
🔬 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?

The token is an identifier, but not _. We prohibit passing _ to macros expecting ident for now.
