Struct Interval

pub struct Interval<T: PartialOrd> {
    pub lb: T,
    pub ub: T,
    pub _marker: PhantomData<T>,
}

The Interval struct represents a range of values with a lower bound (lb) and an upper bound (ub).

Properties:

• lb: The lb property represents the lower bound of the interval. It is of type T, which is a generic type that must implement the PartialOrd trait. This means that the type T must be able to be compared for ordering.
• ub: The ub property represents the upper bound of the interval. It is of type T, which is a generic type that must implement the PartialOrd trait. The PartialOrd trait allows for comparison between values of type T.
• _marker: The _marker field is a marker field that is used to indicate that the generic type T is used in the struct. It is typically used when you want to associate a type parameter with a struct, but you don’t actually need to store any values of that type in the struct.

Fields

lb: T

ub: T

_marker: PhantomData<T>

Implementations

impl<T: PartialOrd> Interval<T>

pub fn new(lb: T, ub: T) -> Self

The function new creates a new instance of a struct with given lower and upper bounds.

Arguments:

• lb: The lb parameter represents the lower bound value. It is of type T, which means it can be any type that implements the necessary traits for the struct.
• ub: The ub parameter represents the upper bound value. It is of type T, which means it can be any type that implements the necessary traits for the struct.

Returns:

The new function is returning an instance of the struct Self.

Examples

use physdes::interval_ai::Interval;
use std::marker::PhantomData;

assert_eq!(Interval::new(1, 2), Interval { lb: 1, ub: 2, _marker: PhantomData });
assert_eq!(Interval::new(2, 1), Interval { lb: 2, ub: 1, _marker: PhantomData });

Trait Implementations

impl<T: Debug + PartialOrd> Debug for Interval<T>

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

Formats the value using the given formatter.

impl<T: PartialOrd> PartialEq for Interval<T>

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

The function checks if two objects have equal values for their “lb” and “ub” fields.

Arguments:

• other: The other parameter is a reference to another object of the same type as Self. In this case, Self refers to the type of the object implementing the eq method.

Returns:

A boolean value is being returned.

Examples

use physdes::interval_ai::Interval;
assert_eq!(Interval::new(1, 2), Interval::new(1, 2));

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<T: PartialOrd> PartialOrd for Interval<T>

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

The function partial_cmp compares the lower bound of self with the upper bound of other and returns the result as an Option of Ordering.

Arguments:

• other: The other parameter is a reference to another object of the same type as self.

Returns:

an Option containing a std::cmp::Ordering value.

Examples

use physdes::interval_ai::Interval;
use std::marker::PhantomData;
assert_eq!(Interval::new(1, 2).partial_cmp(&Interval::new(2, 3)), Some(std::cmp::Ordering::Less));

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.
