Enum relp_num::NonZeroSign

pub enum NonZeroSign {
    Positive,
    Negative,
}

Sign of a nonzero value.

Existing Sign traits, such in num, typically have a third value for the sign of 0. Working with that trait creates many branches or match cases that should never be possible.

Variants

Positive

x > 0

Negative

x < 0

Trait Implementations
