Macro proc_macro::quote::quote

macro_rules! quote {
    () => { ... };
    ($($t:tt)*) => { ... };
}

🔬This is a nightly-only experimental API. (proc_macro_internals #27812)

Simpler version of the real quote! macro, implemented solely through macro_rules, for bootstrapping the real implementation (see the quote function), which does not have access to the real quote! macro due to the proc_macro crate not being able to depend on itself.

Note: supported tokens are a subset of the real quote!, but unquoting is different: instead of $x, this uses (@ expr).
