Enum Sign

pub enum Sign {
    Positive,
    Negative,
}

Specifies how signs should be displayed for numeric values.

The Sign enum controls the display of signs for numeric values in formatted output. It determines whether positive numbers should show a plus sign, only negative numbers should show a minus sign, or no special sign handling should be applied.

Format Specification

In format strings, these correspond to:

• + for Sign::Positive (show signs for both positive and negative numbers)
• - for Sign::Negative (show signs only for negative numbers, default behavior)

Variants

Positive

Always show the sign for numeric values.

Positive numbers will be prefixed with +, and negative numbers with -. This corresponds to the + format specifier.

Negative

Only show the sign for negative numbers.

Negative numbers will be prefixed with -, while positive numbers will have no sign prefix. This is the default behavior and corresponds to the - format specifier.
