Module quote 

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

Quasiquoter

This file contains the implementation internals of the quasiquoter provided by quote!. This quasiquoter uses macros 2.0 hygiene to reliably access items from proc_macro, to build a proc_macro::TokenStream.

Modules

ext 👻 Experimental

Extension traits used by the implementation of quote!. These are defined in separate traits, rather than as a single trait due to ambiguity issues.

Macros

minimal_quote 🔒 Experimental

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.

minimal_quote_ts 🔒 Experimental

minimal_quote_tt 🔒 Experimental

Structs

HasIterator 👻 Experimental

RepInterp 👻 Experimental

ThereIsNoIteratorInRepetition 👻 Experimental

Functions

collect_meta_vars 🔒 Experimental

Helper function to support macro repetitions like $( CONTENTS ) SEP_OPT * in quote!. Recursively collects all Idents (meta-variables) that follow a $ from the given CONTENTS stream, preserving their order of appearance.

quoteExperimental

Quote a TokenStream into a TokenStream. This is the actual implementation of the quote!() proc macro.

quote_spanExperimental

Quote a Span into a TokenStream. This is needed to implement a custom quoter.
