Struct LessThanInvariant

pub struct LessThanInvariant<const N: i32>;

Terms less than a constant (defined by PartialOrd comparison).

Trait Implementations

impl<const N: i32> Clone for LessThanInvariant<N>

fn clone(&self) -> LessThanInvariant<N>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<const N: i32> Debug for LessThanInvariant<N>

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

Formats the value using the given formatter.

impl<const N: i32> Default for LessThanInvariant<N>

fn default() -> LessThanInvariant<N>

Returns the “default value” for a type.

impl<const N: i32> Hash for LessThanInvariant<N>

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl<const N: i32> Ord for LessThanInvariant<N>

fn cmp(&self, other: &LessThanInvariant<N>) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl<const N: i32> PartialEq for LessThanInvariant<N>

fn eq(&self, other: &LessThanInvariant<N>) -> 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.

impl<const N: i32> PartialOrd for LessThanInvariant<N>

fn partial_cmp(&self, other: &LessThanInvariant<N>) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl<const N: i32> Test<i32> for LessThanInvariant<N>

const ADJECTIVE: &str = "positive"

Adjective to describe this test: for example, if we’re testing A, then this is B in “A is not B.”

type Error<'i> = NotLessThan<'i, N> where i32: 'i

An error implementing ::core::fmt::Display. If no error is ever provided, please use ::core::convert::Infallible.

fn test([input]: [&i32; 1]) -> Result<(), Self::Error<'_>>

Check whether a given term satisfies this invariant.
