Enum time::Sign [−][src]
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. Sign
s can also be multiplied and divided by another Sign
, which
follows the same rules as real numbers.
Variants
The only use for this (obtaining the sign of a Duration
) can be replaced with Duration::is_{positive|negative|zero}
A positive value.
The only use for this (obtaining the sign of a Duration
) can be replaced with Duration::is_{positive|negative|zero}
A negative value.
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());
