Functions

func AssertedTypes

func AssertedTypes[G any](values ...any) []G

AssertedTypes casts the provided values to the type G and returns a slice of type G. Panics if any value is not of type G.

func Bytes

func Bytes(value any) ([]byte, error)

Bytes casts the provided value to a byte slice and returns it. It returns an error if the value is not of a type that can be cast to a byte slice.

func NaturalComparable

func NaturalComparable[C comparable](value any) (cmp C, ok bool)

NaturalComparable casts the provided values to the type T as value.

Natural comparable types are the types that are comparable by default, such as primitives, strings, booleans, and complex numbers. See the documentation for the comparable type for more information. https://go.dev/blog/comparable

func Numeric

func Numeric[T nums.Any](value any) (T, error)

Numeric casts the provided value to the type T and returns it. T must be a numeric type. If the value is not of type T, an error is returned.

func Primitive

func Primitive[T prim.Any](value any) (T, error)

Primitive casts the provided value to the type T and returns it. T must be a primitive type. If the value is not of type G, an error is returned.

func PrimitiveComparable

func PrimitiveComparable[T prim.Comparable](value any) (T, error)

PrimitiveComparable casts the provided value to the type T and returns it. T must be a primitive comparable type. If the value is not of type G, an error is returned.

func PrimitiveOrdered

func PrimitiveOrdered[T prim.Ordered](value any) (T, error)

PrimitiveOrdered casts the provided value to the type T and returns it. T must be a primitive ordered type. If the value is not of type G, an error is returned.

func Type

func Type[T any](value any) (cast T, ok bool)

Type casts the provided value to the type T and returns it. It just feels stupid to have a casters package and do not have its most basic use cases.

func Types

func Types[G any](values ...any) (result []G, allMatches bool)

Types casts the provided values to the type G and returns a slice of type G. The second return value allMatches is true if all values were successfully cast to type G, and false otherwise.
