Enum Size 

pub enum Size<T> {
    Empty,
    SinglePoint,
    Finite(T),
    Infinite,
}

Represent a length of the arbitrary interval.

Variants

Empty

Interval containing no points at all.

SinglePoint

A size of interval containing exactly one point (or the finite number of discrete points).

Finite(T)

A finite size of interval bounded in both directions.

Infinite

A size of interval extending infinitely in at least one direction.

Implementations

impl<T> Size<T>

pub const fn is_empty(&self) -> bool

Check whether the size represents an empty interval.

pub fn into_diff(self) -> Option<T>

where T: Zero,

Convert the size into a finite difference value, if possible.

Trait Implementations

impl<T: Clone> Clone for Size<T>

fn clone(&self) -> Size<T>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<T: Debug> Debug for Size<T>

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

Formats the value using the given formatter.

impl<T: PartialEq> PartialEq for Size<T>

fn eq(&self, other: &Size<T>) -> 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.
