Issue ID: 17150
Summary: Add a trait to detect the linkage attribute of classes
and interfaces
Product: D
Version: D2
Hardware: All
OS: All
Status: NEW
Severity: enhancement
Priority: P1
Component: dmd
Assignee: [email protected]
Reporter: [email protected]
Currently extern(C++) interfaces and extern(C++) classes can only be
dinstinguished using compile time introspection on the member functions (with
std.traits.functionLinkage that detects the linkage in the function mangle)
However this kind of introspection is heavy and bug prone (the recurring issue
about protection attribute in __trait(getMember/getOverload)
Two examples of where it would be usefull to have __trait(linkage)
- std.traits.BaseClassesTuple: it only works with D classes so we could filter
the call.
- std.experimental.allocators.allocator.dispose: the overload that takes
interfaces should not work for C++ interfaces.
