Enum BoundErrorKind 

pub enum BoundErrorKind {
    LessThanZero,
    GreaterThanOne,
    Neither,
}

Describes how a value falls outside the closed unit interval [0, 1]

Examples

use unit_interval::{UnitInterval, BoundErrorKind};

let result = UnitInterval::new_checked(-0.5);
assert_eq!(result.unwrap_err().kind(), BoundErrorKind::LessThanZero);

let result = UnitInterval::new_checked(1.5);
assert_eq!(result.unwrap_err().kind(), BoundErrorKind::GreaterThanOne);

let result = UnitInterval::new_checked(f32::NAN);
assert_eq!(result.unwrap_err().kind(), BoundErrorKind::Neither);

Variants

LessThanZero

The value is less than both zero and one

When T::zero() <= val is false but val <= T::one() is true.

GreaterThanOne

The value is greater than both zero and one

When T::zero() <= val is true but val <= T::one() is false.

Neither

The value is neither greater than or equal to zero nor less than or equal to one

When both T::zero() <= val and val <= T::one() are false.

This can mean 2 things:

1. The value is NaN-like
2. The comparison operations (PartialOrd) or Zero or One are incorrectly implemented for the type of the value

Trait Implementations

impl Clone for BoundErrorKind

fn clone(&self) -> BoundErrorKind

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for BoundErrorKind

impl Debug for BoundErrorKind

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Eq for BoundErrorKind

impl PartialEq for BoundErrorKind

fn eq(&self, other: &BoundErrorKind) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
