Trait FixedPoint 

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

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.
