Enum rustc_builtin_macros::format::PositionalNamedArgType

enum PositionalNamedArgType {
    Arg,
    Width,
    Precision,
}

Indicates how positional named argument (i.e. an named argument which is used by position instead of by name) is used in format string

• Arg is the actual argument to print
• Width is width format argument
• Precision is precion format argument Example: `{Arg:Width$.Precision$}

Trait Implementations

impl Debug for PositionalNamedArgType

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

Formats the value using the given formatter.

impl PartialEq<PositionalNamedArgType> for PositionalNamedArgType

fn eq(&self, other: &PositionalNamedArgType) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
