Module syntax::ext::tt::quoted[−][src]

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

this crate is being loaded from the sysroot, an unstable location; did you mean to load this crate from crates.io via Cargo.toml instead?

Structs

Delimited	[ Experimental ] Contains the sub-token-trees of a "delimited" token tree, such as the contents of `(`. Note that the delimiter itself might be `NoDelim`.
SequenceRepetition	[ Experimental ]

KleeneOp	[ Experimental ] A Kleene-style repetition operator for token sequences.
TokenTree	[ Experimental ] Similar to `tokenstream::TokenTree`, except that `$i`, `$i:ident`, and `$(...)` are "first-class" token trees. Useful for parsing macros.

kleene_op	[ Experimental ] Takes a token and returns `Some(KleeneOp)` if the token is `+` `*` or `?`. Otherwise, return `None`.
parse	[ Experimental ] Takes a `tokenstream::TokenStream` and returns a `Vec<self::TokenTree>`. Specifically, this takes a generic `TokenStream`, such as is used in the rest of the compiler, and returns a collection of `TokenTree` for use in parsing a macro.
parse_kleene_op	[ Experimental ] Parse the next token tree of the input looking for a KleeneOp. Returns
parse_sep_and_kleene_op	[ Experimental ] Attempt to parse a single Kleene star, possibly with a separator.
parse_sep_and_kleene_op_2015	[ Experimental ]
parse_sep_and_kleene_op_2018	[ Experimental ]
parse_tree	[ Experimental ] Takes a `tokenstream::TokenTree` and returns a `self::TokenTree`. Specifically, this takes a generic `TokenTree`, such as is used in the rest of the compiler, and returns a `TokenTree` for use in parsing a macro.
