This distributes docs in a separate package called rust-docs. The rust-packaging
project will combine it with Rust and Cargo into a single installer in a variety of formats.
The first six commits are from an earlier PR (#19858) and have already been reviewed. This PR makes an awful hack in the compiler to accommodate slices both natively and in the index a range form. After a snapshot we can hopefully add the new Index impls and then we can remove these awful hacks.

This patch for #15877 uses Antlr's input lookahead (`_input.LA(1) != '.'`) to solve the conflict between the LIT_FLOAT and the range syntax.
Note that in order to execute the grammar tests, #20245 should land first.
This commit performs a second pass over the `std::string` module, performing the
following actions:
* The name `std::string` is now stable.
* The `String::from_utf8` function is now stable after having been altered to
return a new `FromUtf8Error` structure. The `FromUtf8Error` structure is now
stable as well as its `into_bytes` and `utf8_error` methods.
* The `String::from_utf8_lossy` function is now stable.
* The `String::from_chars` method is now deprecated in favor of `.collect()`
* The `String::from_raw_parts` method is now stable
* The `String::from_str` function remains experimental
* The `String::from_raw_buf` function remains experimental
* The `String::from_raw_buf_len` function remains experimental
* The `String::from_utf8_unchecked` function is now stable
* The `String::from_char` function is now deprecated in favor of
`repeat(c).take(n).collect()`
* The `String::grow` function is now deprecated in favor of
`.extend(repeat(c).take(n)`
* The `String::capacity` method is now stable
* The `String::reserve` method is now stable
* The `String::reserve_exact` method is now stable
* The `String::shrink_to_fit` method is now stable
* The `String::pop` method is now stable
* The `String::as_mut_vec` method is now stable
* The `String::is_empty` method is now stable
* The `IntoString` trait is now deprecated (there are no implementors)
* The `String::truncate` method is now stable
* The `String::insert` method is now stable
* The `String::remove` method is now stable
* The `String::push` method is now stable
* The `String::push_str` method is now stable
* The `String::from_utf16` function is now stable after its error type has now
become an opaque structure to carry more semantic information in the future.
A number of these changes are breaking changes, but the migrations should be
fairly straightforward on a case-by-case basis (outlined above where possible).
[breaking-change]
This library is now published on crates.io as the `term` crate, so the in-tree
version is now deprecated. Once stability warnings are enabled, this library
will automatically be gated.
According to http://llvm.org/docs/LangRef.html#data-layout correct syntax
for data layout is `a:<abi>:<pref>` so it looks like `a0:<abi>:<pref>` is
either a typo or outdated syntax (as it goes back pretty deep in time)
The methods `from_bits` and `from_bits_truncate` were missing from the
list of generated methods. Didn't see a useful way to abbreviate, so
added with the same docstrings used in the macro definition.
Since runtime is removed, rust has no tasks anymore and everything is moving
from being task-* to thread-*. Let’s rename TaskRng as well!
This is a breaking change. If a breaking change for consistency is not desired, feel free to close.
Fixes#19707.
In terms of output, it currently uses the form `argument #1`, `argument #2`, etc. If anyone has any better suggestions I would be glad to consider them.
* Both enums already derived `Copy`, but storing them in any
struct/container would prevent implementing `Clone` for said
struct/container even though they should be clonable.
* Also add PartialEq and Eq for good measure.
I would like to look into some issues related to the model lexer #15883.
I stumbled upon 2 minor problems when I tried running the lexer tests:
* antlr did not put the generated files in the correct directory
* grammer/verify.rs did not work with the most recent version of rust
With these changes (and setting CLASSPATH=/usr/share/java/antlr-4.4-complete.jar:$CLASSPATH) I was able to execute the tests.
Note that I just fixed the syntax errors and added `None` as 2. argument of `Literal`. I am not sure if this is correct however. I still have to take a closer look at what verify.rs actually does. Are there any helpful pointers?
I've created a patch for #20226, which maps `EEXIST` to the `PathAlreadyExists` error on Unix. To test this, I use `mkdir`, which raises `EEXIST` if the directory already exists.
On Windows, I map `ERROR_ALREADY_EXISTS` to `PathAlreadyExist`, but I am note sure if `mkdir` on Windows raises `ERROR_ALREADY_EXISTS` and do not have a Windows installation handy for testing.
And I noticed another thing. No error seems to map to `IoErrorKind::PathDoesntExist` and I am wondering what the difference to `FileNotFound` is?
The example derived Hash + Eq on a type that was used as *values* for
a hashmap.. for the example to make sense, we have to use a custom *key*
type.
Write a slightly more involved example, still using Vikings, but this
time as key.
I preferred using String over &str here, since that's the typical usage
and we might want to lead users down that path.
