Let's build PyO3 - first stream!

This was my first stream developing PyO3 live. We took a look into some procedural macro code which needed updating for an upcoming API rewrite for PyO3 0.21. In particular, the changes here were motivated by https://github.com/PyO3/pyo3/pull/3705#discussion_r1443763530 You can see a summary of the proposed API changes summarised at https://github.com/PyO3/pyo3/issues/3382 00:00 Holding screen 09:00 Stream start 12:35 Intro to today's topic 16:00 Quick intro to compiling PyO3 extensions 27:00 Motivation for the upcoming API changes 37:00 Using cargo expand to debug proc macros 42:00 Looking through PyO3's current implementation 1:07:04 Implementation of new functionality 1:43:00 "Into" a new puzzle 1:51:00 Wrapping up If you enjoyed this content and want more of it, or in general want to support development of PyO3, please consider supporting me at https://github.com/sponsors/davidhewitt If you have feedback or ideas of what you'd like to see for future streams, you can contact me via email (see my channel info), Mastodon, or Twitter.
