[][src]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.

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

A value that is exactly zero.

Implementations

impl Sign[src]

pub fn negate(self) -> Self[src]

Return the opposite of the current sign.

assert_eq!(Sign::Positive.negate(), Sign::Negative);
assert_eq!(Sign::Negative.negate(), Sign::Positive);
assert_eq!(Sign::Zero.negate(), Sign::Zero);

pub const fn is_positive(self) -> bool[src]

Is the sign positive?

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

pub const fn is_negative(self) -> bool[src]

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[src]

Is the value exactly zero?

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