Modules
Macros
A type-macro that expands to the name of the Rust type representation of a given token.
Generate code only if feature::make is enabled.
Parse a set of curly braces and expose their content to subsequent parsers.
Parse a set of square brackets and expose their content to subsequent parsers.
Macro for diagnostics purpose to diagnose source code behind it and export it into a string.
Macro to export source code behind a syntax tree into a string.
Macro for diagnostics purpose to print both syntax tree and source code behind it without syntax tree.
Define a type that supports parsing and printing a given identifier as if it were a keyword.
Define a type that supports parsing and printing a multi-character symbol as if it were a punctuation token.
Variadic constructor.
Parse a set of parentheses and expose their content to subsequent parsers.
Parse the input TokenStream of a macro, triggering a compile error if the tokens fail to parse.
Quasi-quotation macro that accepts input like the quote! macro but uses
type inference to figure out a return type for those tokens.
Quasi-quotation macro that accepts input like the quote! macro but uses
type inference to figure out a return type for those tokens.
This macro is [parse_quote!] + quote_spanned!.
Macro to generate syn error either with span of a syntax tree element or with default one proc_macro2::Span::call_site().
Macro for diagnostics purpose to export both syntax tree and source code behind it into a string.
