Struct rustc_builtin_macros::format::PositionalNamedArg

struct PositionalNamedArg {
    ty: PositionalNamedArgType,
    cur_piece: usize,
    inner_span_to_replace: Option<InnerSpan>,
    replacement: Symbol,
    positional_named_arg_span: Span,
    has_formatting: bool,
}

Contains information necessary to create a lint for a positional named argument

Fields

ty: PositionalNamedArgType

cur_piece: usize

The piece of the using this argument (multiple pieces can use the same argument)

inner_span_to_replace: Option<InnerSpan>

The InnerSpan for in the string to be replaced with the named argument This will be None when the position is implicit

replacement: Symbol

The name to use instead of the position

positional_named_arg_span: Span

The span for the positional named argument (so the lint can point a message to it)

has_formatting: bool

Implementations

impl PositionalNamedArg

fn get_positional_arg_spans(
    &self,
    cx: &Context<'_, '_>
) -> (Option<Span>, Option<Span>)

Determines:

1. span to be replaced with the name of the named argument and
2. span to be underlined for error messages

impl Debug for PositionalNamedArg

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
