Issue ID: 15707
Summary: Extend aggregate TypeInfo with information about
`alias this`
Product: D
Version: D2
Hardware: All
OS: All
Status: NEW
Severity: enhancement
Priority: P1
Component: druntime
Assignee: [email protected]
Reporter: [email protected]
Proposal:
enhance TypeInfo so that for a struct like this:
struct S
{
byte[8] x;
int y;
alias y this;
}
.. the following code will be valid:
auto ti = typeid(S.init);
assert (ti.aliasthis.offset == 8);
assert (ti.aliasthis.next == typeid(int.init));
Use case:
RTTI based formatting/logging, most importantly in cases where `alias this`
struct is used as a replacement for typedef.
