type Handle …

// NewHandle returns a handle for a given value.
//
// The handle is valid until the program calls Delete on it. The handle
// uses resources, and this package assumes that C code may hold on to
// the handle, so a program must explicitly call Delete when the handle
// is no longer needed.
//
// The intended use is to pass the returned handle to C code, which
// passes it back to Go, which calls Value.
func NewHandle(v any) Handle { … }

// Value returns the associated Go value for a valid handle.
//
// The method panics if the handle is invalid.
func (h Handle) Value() any { … }

// Delete invalidates a handle. This method should only be called once
// the program no longer needs to pass the handle to C and the C code
// no longer has a copy of the handle value.
//
// The method panics if the handle is invalid.
func (h Handle) Delete() { … }
