The reason given didn't make any sense when I read it when reading through the docs. I think this is more clear. Please let me know it is also more correct.
The impl for [T] also works as impl for slices in general.
By generalizing the impl of StrVector for Vec<Str> to that for
AsSlice<Str>, it becomes much more generic.
Once Iterable is implemented, we will prefer it to AsSlice.
But the with_capacity() part might become tricky.

This breaks code like
```
let t = (42i, 42i);
... t.0::<int> ...;
```
Change this code to not contain an unused type parameter. For example:
```
let t = (42i, 42i);
... t.0 ...;
```

This commit makes `Cow` more usable by allowing it to be applied to
unsized types (as was intended) and providing some basic `ToOwned`
implementations on slice types. It also corrects the documentation for
`Cow` to no longer mention `DerefMut`, and adds an example.
Closes#19123
This commit is an implementation of [RFC 240][rfc] when applied to the standard
library. It primarily deprecates the entirety of `string::raw`, `vec::raw`,
`slice::raw`, and `str::raw` in favor of associated functions, methods, and
other free functions. The detailed renaming is:
* slice::raw::buf_as_slice => slice::from_raw_buf
* slice::raw::mut_buf_as_slice => slice::from_raw_mut_buf
* slice::shift_ptr => deprecated with no replacement
* slice::pop_ptr => deprecated with no replacement
* str::raw::from_utf8 => str::from_utf8_unchecked
* str::raw::c_str_to_static_slice => str::from_c_str
* str::raw::slice_bytes => deprecated for slice_unchecked (slight semantic diff)
* str::raw::slice_unchecked => str.slice_unchecked
* string::raw::from_parts => String::from_raw_parts
* string::raw::from_buf_len => String::from_raw_buf_len
* string::raw::from_buf => String::from_raw_buf
* string::raw::from_utf8 => String::from_utf8_unchecked
* vec::raw::from_buf => Vec::from_raw_buf
All previous functions exist in their `#[deprecated]` form, and the deprecation
messages indicate how to migrate to the newer variants.

Looks like I made my previous PR a little too hastily. =)
This PR fixes a couple issues that I discovered with my previous revision:
1. Updated the errorformat to ignore "pointer lines" so that they don't show up in the output (with quickfix jumping, they're redundant and unnecessary).
2. Renamed a couple variables to be more in line with Cargo's terminology (`g:cargo_toml_name` should now be `g:cargo_manifest_name`).
3. Added support for errors reported with absolute paths (looks to be the case when compiling an executable instead of a library).
4. Most importantly, added support for errors reported while compiling a dependency. When building a Cargo package with local dependencies, if one of those dependencies failed to compile, the quickfix would be completely broken as it assumed that all errors were relative to the local manifest, or the closest Cargo.toml. With this update, it now pays attention to lines that end with `(file://<path>)`, and from then on adjusts all errors to be relative to `<path>`.
As a side note, that `<path>` output is somewhat broken on Windows. While `file:///home/damien/...` on *Nix is a valid URI, `file:///C:/Users/damien/...` on Windows is not, because `C:/` (or whatever the drive is) should take the place of the third slash which is *Nix's root, not be appended to it. I added a workaround for this in my script, but I figured I'd mention it to see if this is a bug in how Rust formats paths.
The struct_variant is not gated anymore. This commit just removes it and the resulting warnings when compiling rust. Now compiles with the snapshot from 11/18 (as opposed to PR #19014)
Right now we'll end up globbing them into the accepted targets and (ever worse) they will override the make variables of real target files because we `include`d everything in that directory.
As a side effect, editors get a better hint on file types.
* Deprecate the free functions in favor of methods, except the two ctors `from_u32` and `from_digit`, whose methods are deprecated.
* Mark the `Char` and `UnicodeChar` traits experimental until we decide for sure that we won't have some sort of inherent methods for primitives.
* The `UnicodeChar` methods related to numerics are now called e.g. `is_numeric` to match the 'numeric' unicode character class, and the `*_digit_radix` methods on `Char` now just called `*_digit`.
* `len_utf8_bytes` -> `len_utf8`
* Converted methods to take self by-value
* Converted `escape_default` and `escape_unicode` to iterators over chars.
* Renamed `is_XID_start`, `is_XID_continue` to `is_xid_start`, `is_xid_continue` to match conventions
This also converts `encode_utf8` and `encode_utf16` to return iterators. I suspect this is not the final form of these methods. Perf is worse (numbers in the commit). Many of the uses ended up being awkward, copying into a buffer then writing that buffer to a `Writer`. It might be more appropriate for these to return `Reader`s instead, but that type is defined in `std`.
Note: although I *did* add the `from_u32` ctor to the `Char` trait, I deprecated it again later, preferring the free ctors.
I've been sitting on this for a while.

This is an initial API stabilization pass for `std::ascii`. Aside from
some renaming to match conversion conventions, and deprecations in favor
of using iterators directly, almost nothing is changed here. However,
the static case conversion tables that were previously public are now private.
The stabilization of the (rather large!) set of extension traits is left
to a follow-up pass, because we hope to land some more general machinery
that will provide the same functionality without custom traits.
