Struct Arg 

pub struct Arg(/* private fields */);

Implementations

impl Arg

pub fn eq_token(&self) -> Option<SyntaxToken<RLanguage>>

The = token of a named argument (name = value), if any.

pub fn name_token(&self) -> Option<SyntaxToken<RLanguage>>

The name token of a named argument — the IDENT/STRING immediately before =. None for a positional argument.

pub fn name(&self) -> Option<SmolStr>

The argument name, unquoted. None for a positional argument.

pub fn is_named(&self) -> bool

pub fn value(&self) -> Option<SyntaxElement<RLanguage>>

The value element: for name = value, the first non-trivia element after =; for a positional argument, its first non-trivia element.
