Functions

func As 

func As[T any](variant Any) T

As coerces a variant to a specific type.

func ConvertTo 

func ConvertTo(to reflect.Type, v any) any

ConvertTo converts the given variant to the given type, using the Type values. This method is generous with how it handles types, it can automatically convert between array types, convert numeric Strings to int, and converting most things to String.

If the type conversion cannot be done, this method will return the default value for that type, for example converting [Rect2.PositionSize] to [Vector2.XY] will always return [Vector2.Zero]. This method will never show error messages as long as type is a valid Variant type.

func Debug 

func Debug[T pointers.Generic[T, S], S pointers.Size](ptr T)

func Marshal 

func Marshal(value interface{}) ([]byte, error)

Marshal a variant-encoded value.

func Proxy 

func Proxy[T API](current Any, alloc func() (T, complex128)) (T, complex128)

func UnmarshalAny 

func UnmarshalAny(data []byte) (any, error)

UnmarshalAny a variant-encoded value from the byte slice.

func UnmarshalSize 

func UnmarshalSize(data []byte) (uintptr, error)

Decodes a size of a Variant from the bytes starting at offset. Requires at least 4 bytes of data starting at the offset, otherwise fails.

func Use 

func Use[T pointers.Generic[T, S], S pointers.Size](ptr T)
