Struct decorum::ConstrainedFloat

#[repr(transparent)]
pub struct ConstrainedFloat<T, P>where
    T: Float + Primitive,
    P: FloatConstraint<T>,{ /* private fields */ }

Floating-point proxy that provides ordering, hashing, and value constraints.

Wraps floating-point values and provides a proxy that implements operation and numerical traits, including Hash, Ord, and Eq. May apply constraints that prevent certain values from occurring (by panicing).

Proxies canonicalize NaN and zero to the forms CNaN and C0 for the following total ordering: [-INF | ... | C0 | ... | INF | CNaN ].

This type is re-exported but should not (and cannot) be used directly. Use the exported type aliases instead (Ordered, NotNan, and Finite).

Implementations

impl<T, P> ConstrainedFloat<T, P>where
    T: Float + Primitive,
    P: FloatConstraint<T>,

pub fn from_inner(value: T) -> Self

Converts a primitive floating-point value into a proxy.

This kind of conversion is the primary way to obtain a proxy. The same behavior is provided by an implemention of the From trait.

Panics

This conversion and the implementation of the From trait will panic if the primitive floating-point value violates the constraints of the proxy.

Examples

Converting primitive floating-point values into proxies:

use decorum::R64;

fn f(x: R64) -> R64 {
    x * 2.0
}

// Conversion using `from_inner`.
let y = f(R64::from_inner(2.0));
// Conversion using `From`/`Into`.
let z = f(2.0.into());

Performing a conversion that panics:

use decorum::R64;

// `R64` does not allow `NaN`s, but `0.0 / 0.0` produces a `NaN`.
let x = R64::from_inner(0.0 / 0.0); // Panics.

pub fn into_inner(self) -> T

Converts a proxy into a primitive floating-point value.

Examples

Converting a proxy into a primitive floating-point value:

use decorum::R64;

fn f() -> R64 {
    // ...
}

let x: f64 = f().into_inner();

pub fn from_subset<Q>(other: ConstrainedFloat<T, Q>) -> Selfwhere
    Q: FloatConstraint<T> + SubsetOf<P>,

Converts a proxy into another proxy that is capable of representing a superset of values.

Examples

Converting between compatible proxy types:

use decorum::{N64, R64};
use num::Zero;

let x = R64::zero();
let y = N64::from_subset(x);

pub fn into_superset<Q>(self) -> ConstrainedFloat<T, Q>where
    Q: FloatConstraint<T> + SupersetOf<P>,

Converts a proxy into another proxy that is capable of representing a superset of values.

Examples

Converting between compatible proxy types:

use decorum::{N64, R64};
use num::Zero;

let x = R64::zero();
let y: N64 = x.into_superset();
