Functions

func Clean

func Clean(elem any)

Clean removes all the elements from the data structure by calling the Clean method if the element implements the Cleaner interface.

Parameters:

• cleaner: The data structure to clean.

func Compare

func Compare[T Comparable](a, b T) (int, bool)

Compare compares two values of the same type that implement the Comparable interface. If the values are equal, the function returns 0. If the first value is less than the second value, the function returns -1. If the first value is greater than the second value, the function returns 1.

Parameters:

• a: The first value to compare.
• b: The second value to compare.

Returns:

• int: -1 if a < b, 0 if a == b, 1 if a > b.
• bool: True if the values are comparable.

Behaviors:

• If the values are not comparable, the function returns false.

func CompareAny

func CompareAny(a, b any) (int, bool)

Compare compares two values of the same type that implement the Comparable interface. If the values are equal, the function returns 0. If the first value is less than the second value, the function returns -1. If the first value is greater than the second value, the function returns 1.

Parameters:

• a: The first value to compare.
• b: The second value to compare.

Returns:

• int: -1 if a < b, 0 if a == b, 1 if a > b.
• bool: True if the values are comparable.

Behaviors:

• If the values are not comparable, the function returns false.

func CompareOf

func CompareOf(a, b any) (int, bool)

CompareOf compares two objects of the same type. If any of the objects implements the Comparer interface, the Compare method is called. Otherwise, the objects are compared using the < and == operators.

Parameters:

• a: The first object to compare.
• b: The second object to compare.

Returns:

• int: The result of the comparison.

func CopyOf

func CopyOf(elem any) any

CopyOf creates a copy of the element by either calling the Copy method if the element implements the Copier interface or returning the element as is.

Parameters:

• elem: The element to copy.

Returns:

• any: A copy of the element.

func EqualOf

func EqualOf(a, b any) bool

EqualOf compares two objects of the same type. If any of the objects implements the Equaler interface, the Equals method is called. Otherwise, the objects are compared using the == operator. However, a is always checked first.

Parameters:

• a: The first object to compare.
• b: The second object to compare.

Returns:

• bool: True if the objects are equal, false otherwise.

Behaviors:

• Nil objects are always considered different.

func Find

func Find[T Comparer](S []T, elem T) (int, bool)

Find is a function that searches for an element in a slice and returns its index.

Parameters:

• slice: The slice to search in.
• elem: The element to search for.

Returns:

• int: The index of the element in the slice.
• bool: A flag indicating if the element was found.

Behaviors:

• This function uses the Binary Search algorithm to find the element.
• The slice must be sorted in ascending order.
• If the element is not found, the index is the position where the element should be inserted to maintain the order of the slice.

func GetOrdinalSuffix

func GetOrdinalSuffix(number int) string

GetOrdinalSuffix returns the ordinal suffix for a given integer.

Parameters:

• number: The integer for which to get the ordinal suffix.

Returns:

• string: The ordinal suffix for the number.

For example, for the number 1, the function returns "1st"; for the number 2, it returns "2nd"; and so on.

func IsComparable

func IsComparable(value any) bool

IsComparable returns true if the value is comparable with other values of the same type using the < and > operators or the Comparable interface.

Parameters:

• value: The value to check.

Returns:

• bool: True if the value is comparable, false otherwise.

func IsEmpty

func IsEmpty(elem any) bool

IsEmpty returns true if the element is empty.

Parameters:

• elem: The element to check.

Returns:

• bool: True if the element is empty, false otherwise.

func RunesOf

func RunesOf(str any) []rune

RunesOf returns the runes of a string. If the string implements the Runer interface, the Runes method is called. Otherwise, the string is converted to a slice of runes.

Parameters:

• str: The string to get the runes from.

Returns:

• []rune: The runes of the string.

func Sort

func Sort[T Comparer](S []T)

Sort is a function that sorts a slice of elements in ascending order.

Parameters:

• slice: The slice to sort.

Behaviors:

• This function uses the Quick Sort algorithm to sort the slice.
• The elements in the slice must implement the Comparer interface.

func StringOf

func StringOf(elem any) string

StringOf converts any type to a string.

Parameters:

• elem: The element to convert to a string.

Returns:

• string: The string representation of the element.

Behaviors:

• String elements are returned as is.
• fmt.Stringer elements have their String method called.
• error elements have their Error method called.
• []byte and []rune elements are converted to strings.
• Other elements are converted to strings using fmt.Sprintf and the %v format.

func TypeOf

func TypeOf(value any) string

TypeOf returns the type of the value as a string.

Parameters:

• value: The value to get the type of.

Returns:

• string: The type of the value.
