pub trait FixedPoint: Sized {
    // Required methods
    fn fixed_mul_floor(self, y: Self, denominator: Self) -> Option<Self>;
    fn fixed_mul_ceil(self, y: Self, denominator: Self) -> Option<Self>;

}

Fixed point trait for computing fixed point calculations with native rust types.

Required Methods

fn fixed_mul_floor(self, y: Self, denominator: Self) -> Option<Self>

Safely calculates floor(x * y / denominator). Returns None if a phantom overflow occurs or if the denominator is 0.

fn fixed_mul_ceil(self, y: Self, denominator: Self) -> Option<Self>

Safely calculates ceil(x * y / denominator). Returns None if a phantom overflow occurs or if the denominator is 0.

fn fixed_div_floor(self, y: Self, denominator: Self) -> Option<Self>

Safely calculates floor(x * denominator / y). Returns None if a phantom overflow occurs or if the denominator is 0.

fn fixed_div_ceil(self, y: Self, denominator: Self) -> Option<Self>

Safely calculates ceil(x * denominator / y). Returns None if a phantom overflow occurs or if the denominator is 0.

Object Safety

This trait is not object safe.
