The R-b stands, just adding in a comment:
I implemented some tests for these methods to make sure everything
worked as expected (they did); but there's an unexpected side-effect:
- *_test.go files cannot `import "C"`
- The fromC / toC methods aren't exported
So it's not possible to do the following check:
var b Defbool
b.Set(true)
cb, err := b.toC()
if ( !C.libxl_defbool_val(cb) ) {
// report an error
}
defbool_test.go can't `import "C"`, so it can't call
C.libxl_defbool_val(). We could make an external xenlighttest package,
but that wouldn't be able to call toC().
(I suppose we could write "proxy" functions for every such function we
might want to check, but that seems excessive.)
