Libs Meeting 2021-05-12

# Libs Meeting 2021-05-12 ###### tags: `Libs Meetings` `Minutes` **Attendees**: ... ## Agenda - [Open action items](https://hackmd.io/ovrbJj6CRduRgSA0Wzg2zg) - Libs team charter - There's many open issues and PRs on the RFCs repository ([link](https://github.com/rust-lang/rfcs/labels/T-libs)) - 'backlog bonanza' meetings like the lang team did? - close issues - move to internals? (disable issues on `rfcs`?) - Josh: ping lang and ask core - Conversion methods to replace `as` ([zulip thread](https://rust-lang.zulipchat.com/#narrow/stream/219381-t-libs/topic/Adding.20methods.20as.20more.20specific.20versions.20of.20.60as.60)) - Originally from lang meeting: lint for `func as i16` -> lint for `pointer as i16` (when it doesn't fit) - `pointer as usize as i16` isn't a great alternative. maybe `thing.truncate()`? `pointer.address()`? `pointer.to_bits()`? - `usize -> u64` function only on 64-bit platforms? - generally in favour, but we'd like more complete proposals. grouping them instead of individual PRs would be nice. - Triage - Anything else?
