Hi,
I am getting an error and don't know why it happens, it might even be a
bug. It is about an assignment to a CStruct variable.
The structure is defined like;
class cairo_path_data_point_t is repr('CStruct') is export {
has num64 $.x;
has num64 $.y;
submethod TWEAK ( :$native-object ) {
$!x = $native-object.x;
$!y = $native-object.y;
}
}
The error is generated when typed variables are used (below, $x is also
a cairo_path_data_point_t);
my cairo_path_data_point_t $p1 = $x;
or
my cairo_path_data_point_t $p1 =
cairo_path_data_point_t.new(:native-object($x));
but not with
my cairo_path_data_point_t $p1 .= new(:native-object($x));
or
my $p1 = $x;
After which all fields in the structure are happely accessable using $p1!
The error is
Type check failed in assignment to $p1; expected cairo_path_data_point_t
but got cairo_path_data_point_t.new(x => 0e0, y => 0e0)
Raku version: 2020.06-7-gf1960baa9 built on MoarVM version
2020.06-6-gbf6af07de
implementing Raku 6.d.
The content of the structure does not matter, I've seen it with other
structures too.
Regards,
Marcel
