Trait Magnitude 

pub trait Magnitude:
    Copy
    + PartialEq
    + PartialOrd {
    const ZERO: Self;

    // Required methods
    fn abs_diff(self, other: Self) -> Self;
    fn checked_add(self, other: Self) -> Option<Self>;
    fn checked_sub(self, other: Self) -> Option<Self>;

    // Provided method
    fn is_zero(self) -> bool { ... }
}

Trait for unsigned numeric types supporting arithmetic operations.

This trait defines the core operations needed for currency magnitude types like Amount and Fee.

Required Associated Constants

const ZERO: Self

The zero value for this type.

Required Methods

fn abs_diff(self, other: Self) -> Self

Returns the absolute difference between self and other.

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

Checked addition. Returns None if overflow occurred.

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

Checked subtraction. Returns None if underflow occurred.

Provided Methods

fn is_zero(self) -> bool

Returns true if this value is zero.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
