Hi,
I know there are concerns about struct initialization in method
calls but what is about struct initializer in UDA?
Scenario: I want to set several UDA values. At the moment I
have to create for each value a structure with exactly 1 field.
But it would be quite nice if I could use struct initialization
to group these values:
struct Field
{
string location;
string locationName;
}
struct Foo
{
@A = {locationName: "B"} int c; // <------------------
}
void main() {}
Of course the syntax is questionable, it is just a proposal.
What do you think?
Kind regards
André
I'm not sure if it isi what you're looking for but you can do
struct Field
{
string location;
string locationName;
}
struct Foo
{
@Field("","B") int c;
}
We use this for our compiler recognised attributes in LDC, see
llvmAttr for an example
