What's wrong?
HashSet has a disabled default constructor; you need to supply
the allocator instance to the constructor here
https://github.com/nordlow/
justd/blob/master/containers_ex.d#L17
Doesn't work.
If I change
auto set = HashSet!(E, Allocator)();
to
auto set = HashSet!(E, Allocator)(Allocator());
it errors as
containers_ex.d(17,38): Error: constructor
containers.hashset.HashSet!(const(int), Mallocator, generateHash,
false).HashSet.this (ulong bucketCount) is not callable using
argument types (Mallocator)
containers_ex.d(30,16): Error: template instance
containers_ex.hashSet!(Mallocator, const(int)[]) error
instantiating
containers_ex.d(35,5): Error: static assert (is(typeof(__error)
== const(int)*)) is false
My existing call to
auto set = HashSet!(E, Allocator)();
works for Mallocator as in
https://github.com/nordlow/justd/blob/master/containers_ex.d#L17
but not for
InSituRegion!(1024*1024, T.alignof)
Why? Please, help.
