Trait core::num::SignedIntUnstable

pub trait SignedInt: Int + Neg<Self> {
    fn abs(self) -> Self;
    fn signum(self) -> Self;
    fn is_positive(self) -> bool;
    fn is_negative(self) -> bool;
}

A built-in two's complement integer.

Required Methods

fn abs(self) -> Self

Computes the absolute value of self. Int::min_value() will be returned if the number is Int::min_value().

fn signum(self) -> Self

Returns a number representing sign of self.

• 0 if the number is zero
• 1 if the number is positive
• -1 if the number is negative

fn is_positive(self) -> bool

Returns true if self is positive and false if the number is zero or negative.

fn is_negative(self) -> bool

Returns true if self is negative and false if the number is zero or positive.
