Pass formatter in TryFromSliceError Display impl

2017-09-29T15:26:19+00:00

Make TryFromSliceError::__description unstable

2017-09-29T15:20:21+00:00

Enforces use of Error::description instead.

Implement Error trait for TryFromSliceError

Implement TryFrom for array reference types

There are many cases where a buffer with a static compile-time size is preferred over a slice with a dynamic size. This allows for performing a checked conversion from &[T] to &[T; N]. This may also lead to compile-time optimizations involving [T; N] such as loop unrolling.

Auto merge of #43690 - scalexm:issue-28229, r=nikomatsakis

Generate builtin impls for `Clone` This fixes a long-standing ICE and limitation where some builtin types implement `Copy` but not `Clone` (whereas `Clone` is a super trait of `Copy`). However, this PR has a few side-effects: * `Clone` is now marked as a lang item. * `[T; N]` is now `Clone` if `T: Clone` (currently, only if `T: Copy` and for `N <= 32`). * `fn foo<'a>() where &'a mut (): Clone { }` won't compile anymore because of how bounds for builtin traits are handled (e.g. same thing currently if you replace `Clone` by `Copy` in this example). Of course this function is unusable anyway, an error would pop as soon as it is called. Hence, I'm wondering wether this PR would need an RFC... Also, cc-ing @nikomatsakis, @arielb1. Related issues: #28229, #24000.
