Struct Quantity

pub struct Quantity(/* private fields */);

An arbitrary precision unsigned integer.

Implementations

impl Quantity

pub fn checked_sub(&self, other: &Quantity) -> Option<Quantity>

Subtracts two numbers, checking for underflow. If underflow happens, None is returned.

pub fn checked_div(&self, other: &Quantity) -> Option<Quantity>

Divides two numbers, checking for underflow, overflow and division by zero. If any of that happens, None is returned.
