Struct rustfmt_nightly::macros::MacroArgParser

source ·
struct MacroArgParser {
    buf: String,
    start_tok: Token,
    is_meta_var: bool,
    last_tok: Token,
    result: Vec<ParsedMacroArg>,
}
Expand description

Parses macro arguments on macro def.

Fields§

§buf: String

Either a name of the next metavariable, a separator, or junk.

§start_tok: Token

The first token of the current buffer.

§is_meta_var: bool

true if we are parsing a metavariable or a repeat.

§last_tok: Token

The last token parsed.

§result: Vec<ParsedMacroArg>

Holds the parsed arguments.
