Structs & Interfaces

The basic structs are there for the majority use but there are other implementations that may benefit from added properties.

It is of key importance that a range is valid upon creation so the subsequent validations are not necessary.

readonly struct Boundary<T>

Implements IComparable<T> and implicitly converts to T and declares a boolean .Inclusive. When using Range<Boundary<T>>, this allows for differentiating if a value can be equal to the boundary value or only up to it.

readonly struct Range<T>

Where T implements IComparable<T> and the .Low must be less than or equal to the .High value.

Range<int> Example

var intRange = Range.Create(5, 20);

Range<Boundary<int>> Examples

// 0 < value < 100
var between = Range.Between(0, 100);
var aboveBelow = Range.Above(0).Below(100);

// 0 <= value <= 100
var inclusive = Range.Include(0, 100);
var fromTo = Range.From(0).To(100);

// 0 <= value < 100
var fromBelow = Range.From(0).Below(100);

// 0 < value <= 100
var aboveTo = Range.Above(0).To(100);

Extensions

IRange<Boundary<T>>.Contains<T>(T value)

Does the value (T) exist within the range?

IComparable<T>.IsInRange<T>(T min, T max)

Is the value of the comparable in the range?

Examples

4.IsInRange(2, 6) // true
4.IsInRange(4, 6) // true
100.IsInRange(-5, 50) // false
100.IsInRange(-5, 100) // true

IComparable<T>.IsInBounds<T>(T min, T max)

Is the value of the comparable between the bounds?

Examples

4.IsInRange(2, 6) // true
4.IsInRange(4, 6) // false
100.IsInRange(-5, 50) // false
100.IsInRange(-5, 100) // false
