Last Week's Minutes

• Announcements
  • None this week
• embedded-hal
  • New PR adding futures-based traits https://github.com/rust-embedded/embedded-hal/pull/285
    • Lots of discussion about these proposed traits
    • Should they be unsafe?
    • Could Rust gain a way to indicate "must not leak"?
    • How to handle full-duplex? (perhaps new traits to take either two separate buffers or just one in-place buffer)
    • Should they use slices (yes)
    • Should they use embedded-dma buffers? (probably no)

Last Week's Minutes

• Announcements
  • IRC channel operational on Libera
• cross
  • Release?
  • Post call for maintainers
• embedded-hal
  • Rename send to write https://github.com/rust-embedded/embedded-hal/pull/281
  • blocking::serial names https://github.com/rust-embedded/embedded-hal/pull/280
  • both PRs discussed, so far conclusion is:
    * remove prelude so we can easily have overlapping method names between traits
    * update traits to make send/write/bwrite/etc methods all consistent across blocking/nonblocking traits
    * essentially, approve both these PRs and also remove the prelude
• blog
  • Publish once we can add cross call for help
