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 $$
.
