Module `quote`

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

Structs

Functions

collect_meta_vars 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.
quote Quote a TokenStream into a TokenStream. This is the actual implementation of the quote!() proc macro.
quote_span Quote a Span into a TokenStream. This is needed to implement a custom quoter.

Macros

minimal_quote 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.
