It has binary to text conversion functionality for various types. I don't exactly know what Kaare needs, but that seems like a relevant need. - Andres -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
Re: [HACKERS] Rust bindings to pgtypes lib
I agree with Michael Meskes that duplicating the code is probably not a good idea. Now I see other rust crates just depend on the right libraries to be installed by the developer, so I'll punt the problem until it bites me for real. This confuses me, though > Indeed.

If so, perhaps it would be an idea to mention that somewhere in the docs. Just reading them, it would seem to be a nice interface to a library that can do datetime and arbitrary numeric calculation for you. Both areas are very hard to get right. No problem on my part. The target of my small project was to learn some rust by throing myself at it. And I learned more than expected, so the outcome is already fine. If the resulting project also could be of use to me and anybody else, it would just be an extra win. -- Med venlig hilsen Kaare Rasmussen, Jasonic Jasonic: Nordre Fasanvej 12, 2000 Frederiksberg -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers

However, it could be argued that the code is not duplication (anymore) but a separate implementation of these datatypes. >> I'm not aware of any other language binding for pgtypeslib. > > Some people use http://libpqtypes.esilo.com/ Never before saw this.

I'm quite strongly against exposing / using pgtypeslib in more places. If anything it should be phased out. Because that code is definitely not always kept up2date, and it's a lot of work to do so. If anything the code should be rewritten to *not* require so much duplication, then we could talk. > > How much of the source tree would I have to carve out? > > Or from another perspective; how do other language (if any) solve this? > > I'm not aware of any other language binding for pgtypeslib.

Makefile.global is mostly included for some rules and other than some includes I don't know what else is taken from ecpg. However, there are a couple small files that are taken from teh backend source tree, like pgstrcasecmp.c > How much of the source tree would I have to carve out? > Or from another perspective; how do other language (if any) solve this?
