Detailed Description

template<typename Descriptor, bool Lazy = false, template< typename Type > class Allocator = xcallocator>
class hash_table< Descriptor, Lazy, Allocator >

User-facing hash table type.

  The table stores elements of type Descriptor::value_type and uses
  the static descriptor functions described at the top of the file
  to hash, compare and remove elements.

  Specify the template Allocator to allocate and free memory.
    The default is xcallocator.

    Storage is an implementation detail and should not be used outside the
    hash table code.

of the table after the call will be about 50%.  Naturally the hash
table must already exist.  Remember also that the place of the
table entries is changed.  If memory allocation fails, this function
will abort.

Similar to find_slot, but without several unwanted side effects:
 - Does not call equal when it finds an existing entry.
 - Does not change the count of elements/searches/collisions in the
   hash table.
This function also assumes there are no deleted entries in the table.
HASH is the hash value for the element to be inserted.

This function searches for a hash table slot containing an entry
equal to the given COMPARABLE element and starting with the given
HASH.  To delete an entry, call this with insert=NO_INSERT, then
call clear_slot on the slot returned (possibly after doing some
checks).  To insert an entry, call this with insert=INSERT, then
write the value you want into the returned slot.  When inserting an
entry, NULL may be returned if memory allocation fails.
