#[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}

Expand description

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.

Variants

`Positive`

👎 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}

A positive value.

`Negative`

👎 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}

A negative value.

`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}

A value that is exactly zero.

Implementations

source

impl Sign

source

pub fn negate(self) -> Self

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);

source

pub const fn is_positive(self) -> bool

Is the sign positive?

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

source

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());

source

pub const fn is_zero(self) -> bool

Is the value exactly zero?

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