ccan includes many modules which use macro wrappers to make typesafe
pseudo-templated versions of a basic algorithm or data structure.
This series implements several extensions to the tcon module to enable
yet another approach to this. The advantage of this new method is
that it's able to store a variety of "template" information into a
type or variable declaration. That means that a module using this
technique can implement typesafe wrappers which can obtain the type
information they need from that initial declaration avoiding the need
to respecify types or field members in multiple places.
The last two patches in the series apply this approach to the lstack
and lqueue modules, giving them a nicer typesafe interface.
Changes since v1:
* More macros to access the normal tcon options for the type
canaries built into TCON_CONTAINER
* Macro ti directly access to the offset stored in a TCON_CONTAINER
* TCON_CONTAINER stores the type canaries as the type itself, rather
than a pointer to it. That matches the rest of tcon better, and
plays nicer in conjuction with total_order_cast() from the order
module.
* Fixed the problem that broke ccanlint. It was a ": " where there
should have been a " - ". Really.
David Gibson (6):
tcon: Add an alternate way of building type canaries
tcon: Add tcon_sizeof() helper
tcon: Encode integer values into "type" canaries
tcon: Encode information on container members in "type" canaries
lstack: Streamline interface with TCON_CONTAINER
lqueue: Streamline interface with TCON_CONTAINER
