impl PerThing for Permill[src]

type Inner = u32

The data type used to build this per-thingy.

type Upper = u64

A data type larger than Self::Inner, used to avoid overflow in some computations. It must be able to compute ACCURACY^2. Read more

fn deconstruct(self) -> Self::Inner[src]

Consume self and return the number of parts per thing.

fn from_parts(parts: Self::Inner) -> Self[src]

Build this type from a number of parts per thing.

fn from_fraction(x: f64) -> Self[src]

NOTE: saturate to 0 or 1 if x is beyond [0, 1]

impl Saturating for Permill[src]

fn saturating_add(self, rhs: Self) -> Self[src]
