Hi there!
I intend to create an easy technique to transform GO standard kind (int( 8/16/32)/ uint( 8/16/32)) to cgo kind (C.int/ C.uint e.t.c.)
I intend to make use of generics yet satisfied an issue with type-casting.
see the adhering to code:
// wrapCType is a common technique to transform GOTYPE (int32/float32 e.t.c.) right into CTYPE (c_int/ c_float e.t.c.).
func wrapCType[CTYPE any, GOTYPE any]( goValue * GOTYPE) (covered * CTYPE, finisher func()) {
if goValue!= nil {
cValue:= CTYPE( any kind of(* goValue)).
covered = && cValue.
finisher = func() {
* goValue = GOTYPE( any kind of( cValue)).
}
} else {
finisher = func() {}
}
return.
}
This does not function because CTYPE and also GOTYPE might be anything, so you can not simply make use of type-conversion phrase structure. You could have the ability to do this with restrictions on CTYPE and also GOTYPE similar to this:
kind CNumber user interface C.double.
kind GoNumber user interface ~ uint32
func wrapCType[CTYPE CNumber, GOTYPE GoNumber]( goValue * GOTYPE) (covered * CTYPE, finisher func()).
However I’m uncertain; I have not gone to a computer system for a however and also the Go play ground does not function when you import "C"
