Enum time::Sign

#[repr(i8)]pub enum Sign {
    Positive,
    Negative,
    Zero,
}

👎 Deprecated since 0.2.7:

The only use for this (obtaining the sign of a Duration) can be replaced with Duration::is_{positive|negative|zero}

Contains the sign of a value: positive, negative, or zero.

For ease of use, Sign implements [Mul] and [Div] on all signed numeric types. Signs can also be multiplied and divided by another Sign, which follows the same rules as real numbers.

Implementations

impl Sign

pub fn negate(self) -> Self

assert!(Sign::Positive.is_positive());
assert!(!Sign::Negative.is_positive());
assert!(!Sign::Zero.is_positive());

pub const fn is_negative(self) -> bool

Is the sign negative?

assert!(!Sign::Positive.is_negative());
assert!(Sign::Negative.is_negative());
assert!(!Sign::Zero.is_negative());

pub const fn is_zero(self) -> bool
