Subteam report: libs 2015-10-23

Highlights

This week was an exciting week in the land of libraries as our triage meeting decided on the set of APIs that are going to be stable in 1.5 (coming out next week!). The list of tracking issues we triaged, along with decisions, are:

• libcore - punted to the 1.6 cycle
• libcore float support - punted to the 1.6 cycle
• fs::canonicalize - stabilized
• fs::PathExt - stablized as inherent methods on Path
• Formatter flag/option accessors - stabilized
• as_slice - not stabilized
• RefCell::borrow_state - not stabilized
• misc errors in libstd - stabilized
• iterator comparisons - stabilized
• the slice_splits feature - stabilized
• str::match_indices - stabilized
• Condvar::wait_timeout - stabilized
• slice::ref_slice - deprecated
• iter::range_inclusive - deprecated
• char::from_u32_unchecked - stabilized
• VecDeque extra methods - stabilized (a subset)
• Vec::resize - stabilized
• str::slice_mut_unchecked - stabilized
• os::unix::fs::FileTypeExt - stabilized
• dynamic_lib - deprecatedc
• BinaryHeap - stabilized (a subset)

We didn't get a chance to circle around back to the last week's FCP RFCs, so they'll remain as such for another week. As a reminder, those RFCs are:

• FCP PR #1291 RFC: Promote the libc crate from the nursery
• FCP PR #1307 Add some additional utility methods to OsString and OsStr

At this time we'd also like to draw attention to the following RFCs:

• PR #1288 - Improvements to the Time APIs, this RFC is likely to enter FCP soon.
• PR #1323 - RFC: Amend recover with a PanicSafe bound, this is a continuation of RFC 1236 which proposed stabilizing panic::recover with just the 'static bound.
