Trait FixedPointOps

pub trait FixedPointOps<const DECIMALS: u8>: MulDiv + Num {
    const UNIT: Self;

    // Required method
    fn checked_pow_fixed(&self, exponent: &Self) -> Option<Self>;
}

Number type with the required properties for implementing Fixed.

Required Associated Constants

const UNIT: Self

The unit value (i.e. the value “one”) which is expected to be pow(10, DECIMALS).

Required Methods

fn checked_pow_fixed(&self, exponent: &Self) -> Option<Self>

Fixed point power.

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.

Implementations on Foreign Types

impl<const DECIMALS: u8> FixedPointOps<DECIMALS> for u64

fn checked_pow_fixed(&self, exponent: &Self) -> Option<Self>

Fixed point power.

Notes

The code that calculates exponents behaves inconsistently depending on whether the exponent is a whole unit or not. Therefore, to avoid issues, we should use only unit exponents until we implement better algorithms.

const UNIT: Self

impl<const DECIMALS: u8> FixedPointOps<DECIMALS> for u128

fn checked_pow_fixed(&self, exponent: &Self) -> Option<Self>

Fixed point power.

Notes

The code that calculates exponents behaves inconsistently depending on whether the exponent is a whole unit or not. Therefore, to avoid issues, we should use only unit exponents until we implement better algorithms.
