Enum rustfmt_nightly::macros::MacroArgKind

source · [−]

enum MacroArgKind {
    MetaVariable(Symbol, String),
    Repeat(DelimToken, Vec<ParsedMacroArg>, Option<Box<ParsedMacroArg>>, Token),
    Delimited(DelimToken, Vec<ParsedMacroArg>),
    Separator(String, String),
    Other(String, String),
}

Variants

`MetaVariable(Symbol, String)`

e.g., $x: expr.

`Repeat(DelimToken, Vec<ParsedMacroArg>, Option<Box<ParsedMacroArg>>, Token)`

Tuple Fields

0: DelimToken

(), [] or {}.

1: Vec<ParsedMacroArg>

Inner arguments inside delimiters.

2: Option<Box<ParsedMacroArg>>

Something after the closing delimiter and the repeat token, if available.

3: Token

The repeat token. This could be one of *, + or ?.

e.g., $($foo: expr),*

`Delimited(DelimToken, Vec<ParsedMacroArg>)`

e.g., [derive(Debug)]

`Separator(String, String)`

A possible separator. e.g., , or ;.

`Other(String, String)`

Other random stuff that does not fit to other kinds. e.g., == foo in ($x: expr == foo).
