Enum rustfmt_nightly::macros::MacroArgKind
source · enum MacroArgKind {
MetaVariable(Symbol, String),
Repeat(Delimiter, Vec<ParsedMacroArg>, Option<Box<ParsedMacroArg>>, Token),
Delimited(Delimiter, Vec<ParsedMacroArg>),
Separator(String, String),
Other(String, String),
}
Variants§
MetaVariable(Symbol, String)
e.g., $x: expr
.
Repeat(Delimiter, Vec<ParsedMacroArg>, Option<Box<ParsedMacroArg>>, Token)
Tuple Fields
§
1: Vec<ParsedMacroArg>
Inner arguments inside delimiters.
§
2: Option<Box<ParsedMacroArg>>
Something after the closing delimiter and the repeat token, if available.
e.g., $($foo: expr),*
Delimited(Delimiter, 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)
.

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...)
attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
