Macros

Token

A type-macro that expands to the name of the Rust type representation of a given token.

_if_make

Generate code only if feature::make is enabled.

braced

Parse a set of curly braces and expose their content to subsequent parsers.

bracketed

Parse a set of square brackets and expose their content to subsequent parsers.

code_diagnostics_str

Macro for diagnostics purpose to diagnose source code behind it and export it into a string.

code_export_str

Macro to export source code behind a syntax tree into a string.

code_print

Macro for diagnostics purpose to print both syntax tree and source code behind it without syntax tree.

custom_keyword

Define a type that supports parsing and printing a given identifier as if it were a keyword.

custom_punctuation

Define a type that supports parsing and printing a multi-character symbol as if it were a punctuation token.

make

Variadic constructor.

parenthesized

Parse a set of parentheses and expose their content to subsequent parsers.

parse_macro_input

Parse the input TokenStream of a macro, triggering a compile error if the tokens fail to parse.

parse_qt

Quasi-quotation macro that accepts input like the quote! macro but uses type inference to figure out a return type for those tokens.

parse_quote

Quasi-quotation macro that accepts input like the quote! macro but uses type inference to figure out a return type for those tokens.

parse_quote_spanned

This macro is parse_quote! + quote_spanned!.

qt

The whole point.

syn_err

Macro to generate syn error either with span of a syntax tree element or with default one proc_macro2::Span::call_site().

tree_diagnostics_str

Macro for diagnostics purpose to export both syntax tree and source code behind it into a string.

tree_print

Macro for diagnostics purpose to print both syntax tree and source code behind it with syntax tree.

types
