Enum Sign 

pub enum Sign {
    Positive,
    Negative,
}

An enum representing the sign of a number

A sign can be converted to or from a boolean value, assuming true is Negative.

Variants

Positive

Negative

Implementations

impl Sign

pub const fn as_sign_str(self, sign_plus: bool) -> &'static str

Return the sign as a string slice for formatting.

Returns "-" for Negative, "+" for Positive when sign_plus is true, or "" for Positive when sign_plus is false.

Examples

assert_eq!(Sign::Negative.as_sign_str(false), "-");
assert_eq!(Sign::Positive.as_sign_str(true), "+");
assert_eq!(Sign::Positive.as_sign_str(false), "");
