# [−][src]Macro proc_macro::quote

    macro_rules! quote {
        () => { ... };
    }

🔬 This is a nightly-only experimental API. (`proc_macro_quote` #54722)

`quote!(..)` accepts arbitrary tokens and expands into a `TokenStream` describing the input. For example, `quote!(a + b)` will produce a 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 `$$`.

This is a dummy macro, the actual implementation is in `quote::quote`.`

## Search Tricks

Prefix searches with a type followed by a colon (e.g., `fn:`) to restrict the search to a given type.

Accepted types are: `fn`, `mod`, `struct`, `enum`, `trait`, `type`, `macro`, and `const`.

Search functions by type signature (e.g., `vec -> usize` or `* -> vec`)

Search multiple things at once by splitting your query with comma (e.g., `str,u8` or `String,struct:Vec,test`)
