pub macro quote($($t:tt)*) { ... }
🔬This is a nightly-only experimental API. (
proc_macro_quote #54722)Expand description
quote!(..) accepts arbitrary tokens and expands into a TokenStream describing the input.
For example, quote!(a + b) will produce an expression, that, when evaluated, constructs
the TokenStream [Ident("a"), Punct('+', Alone), Ident("b")].
Unquoting is done with $, and works by taking the single next ident as the unquoted term.
To quote $ itself, use $$.
