Common trait for all integers.

Required Methods

fn integer_is_even(&self) -> bool

Returns true if this integer is even.

fn integer_is_multiple_of(&self, other: &Self) -> bool

Returns true if this integer is a multiple of the other.

fn integer_is_prime(&self) -> Option<bool>

Returns Some(true) if this integer is prime, Some(false) if it’s not prime, or None if it can not be determined.

Returns None if this integer can’t be represented as a usize, or as a u32 in no-std.

fn integer_gcd(&self, other: &Self) -> Option<Self>

where Self: Sized,

Calculates the Greatest Common Divisor of this integer and other.

Returns None if the operation can’t return an integer of the same kind, e.g. for a NegativeInteger.

fn integer_lcm(&self, other: &Self) -> Option<Self>

where Self: Sized,

Calculates the Lowest Common Multiple of this integer and other.

Returns None if the operation can’t return an integer of the same kind, e.g. for NegativeInteger.

fn integer_digits(&self) -> usize

Returns the number of digits in base 10, without the sign.

Provided Methods

fn integer_is_odd(&self) -> bool

Returns true if this integer is odd.

fn integer_is_divisor_of(&self, other: &Self) -> bool

Returns true if this integer is a divisor of the other.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
