Thanks for the pull request, and welcome! The Rust team is excited to review your changes, and you should hear from @estebank (or someone else) soon. If any changes to this PR are deemed necessary, please add them as extra commits. This ensures that the reviewer can see what has changed since they last reviewed the code. Due to the way GitHub handles out-of-date commits, this should also make it reasonably obvious what issues have or haven't been addressed. Large or tricky changes may require several passes of review and changes. Please see the contribution instructions for more information. |
Support for both can be useful when creating new firmware, boot loaders, or embedded operating systems.

Version 1.51.0 (2021-03-25)
============================
Language
--------
- [You can now parameterize items such as functions, traits, and
`struct`s by constant values in addition to by types and
lifetimes.][79135] Also known as "const generics" E.g. you can
now write the following. Note: Only values of primitive integers,
`bool`, or `char` types are currently permitted.
```rust
struct GenericArray<T, const LENGTH: usize> {
inner: [T; LENGTH]
}
impl<T, const LENGTH: usize> GenericArray<T, LENGTH> {
const fn last(&self) -> Option<&T> {
if LENGTH == 0 {
None
} else {
Some(&self.inner[LENGTH - 1])
}
}
}
```
Compiler
--------
- [Added the `-Csplit-debuginfo` codegen option for macOS platforms.][79570]
This option controls whether debug information is split across
multiple files or packed into a single file. **Note** This option
is unstable on other platforms.
- [Added tier 3\* support for `aarch64_be-unknown-linux-gnu`,
`aarch64-unknown-linux-gnu_ilp32`, and
`aarch64_be-unknown-linux-gnu_ilp32` targets.][81455]
- [Added tier 3 support for `i386-unknown-linux-gnu` and
`i486-unknown-linux-gnu` targets.][80662]
- [The `target-cpu=native` option will now detect individual features
of CPUs.][80749]
- [Rust now uses `inline-asm` for stack probes when used with LLVM
11.0.1+][77885]
\* Refer to Rust's [platform support page][forge-platform-support]
for more information on Rust's tiered platform support.

+ Sync` object.][80945]

E>>>`.][80968]
- [`unsigned_abs` is now implemented for all signed integer types.][80959]
- [`io::Empty` now implements `io::Seek`.][78044]
- [`rc::Weak<T>` and `sync::Weak<T>`'s methods such as `as_ptr`
are now implemented for `T: ?Sized` types.][80764]

Cargo
-----
- [Added the `split-debuginfo` profile option to control the -Csplit-debuginfo
codegen option.][cargo/9112]
- [Added the `resolver` field to `Cargo.toml` to enable the new
feature resolver and CLI option behavior.][cargo/8997] Version
2 of the feature resolver will try to avoid unifying features of
dependencies where that unification could be unwanted. Such as
using the same dependency with a `std` feature in a build scripts
and proc-macros, while using the `no-std` feature in the final
binary. See the [Cargo book documentation][feature-resolver@2.0]
for more information on the feature.
Rustdoc
-------
- [Rustdoc will now include documentation for methods available
from `Deref` traits.][80653]
- [You can now provide a `--default-theme` flag which sets the
default theme to use for documentation.][79642]
Various improvements to intra-doc links:
- [You can link to non-path primitives such as `slice`.][80181]
- [You can link to associated items.][74489]
- [You can now include generic parameters when linking to items,
like `Vec<T>`.][76934]
Misc
----
- [You can now pass `--include-ignored` to tests (e.g. with
`cargo test -- --include-ignored`) to include testing tests marked
`#[ignore]`.][80053]
Compatibility Notes
-------------------
- [WASI platforms no longer use the `wasm-bindgen` ABI, and instead
use the wasm32 ABI.][79998]
- [`rustc` no longer promotes division, modulo and indexing operations
to `const` that could fail.][80579]
- [The minimum version of glibc for the following platforms has
been bumped to version 2.31 for the distributed artifacts.][81521]
- `armv5te-unknown-linux-gnueabi`
- `sparc64-unknown-linux-gnu`
- `thumbv7neon-unknown-linux-gnueabihf`

Pkgsrc changes:
* Add support for the big-endian arm64 NetBSD target (aarch64_be).
* On NetBSD/i386, use the i586 (pentium) bootstrap kit variant in
preference to i686.
* Adjust patches, re-compute line offsets, re-compute crate checksums.
* Remove a patch which was either integrated upstream and/or no longer
applies.
* Bump bootstraps to 1.50.0.
* Move conditionals until after bsd.prefs.mk so that they work...
* Default to "dist" build target if cross-compiling, but allow
also to override via rust.BUILD_TARGET.
* Allow overriding MAKE_JOBS_SAFE via rust.MAKE_JOBS_SAFE if you
want a different trade-off between occasional breakage and performance.
* Adjust platform.mk according to work already done in wip/rust/
* Add a patch to optimize the install.sh script used to install binary
bootstraps to not do so many forks; use case/esac and parameter expansion
instead of grep, sed and cut.
* Drop building documentation for the binary bootstrap kits. This will
also impact the lang/rust-bin package. For full documentation, build
or install lang/rust as a package.
