Trait MinNumTraits

pub trait MinNumTraits:
    Sized
    + Copy
    + TryFrom<u32> {
    const ZERO: Self;

    // Required methods
    fn checked_mul(self, rhs: Self) -> Option<Self>;
    fn checked_add(self, rhs: Self) -> Option<Self>;
    fn checked_sub(self, v: Self) -> Option<Self>;

    // Provided method
    fn from_u32(n: u32) -> Option<Self> { ... }
}

minimal subset of traits used by to_signed_with_radix and to_unsigned_with_radix

Required Associated Constants

const ZERO: Self

the 0 value for this type

Required Methods

fn checked_mul(self, rhs: Self) -> Option<Self>

the checked multiplication operation for this type

fn checked_add(self, rhs: Self) -> Option<Self>

the chekced addition operation for this type

fn checked_sub(self, v: Self) -> Option<Self>

the checked subtraction operation for this type

Provided Methods

fn from_u32(n: u32) -> Option<Self>

convert from a unsigned 32-bit word

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.
