netbsd-srcmastr pushed a commit to NetBSD/pkgsrc that referenced this pull request Mar 3, 2019
Pkgsrc changes:
 * Bump required rust version to build to 1.32.0.
 * Adapt patches to changed file locations.
 * Since we now patch some more vendor/ modules, doctor the corresponding
   .cargo-checksum.json files accordingly

Upstream changes:

Version 1.33.0 (2019-02-28)
==========================

Language
--------
- [You can now use the `cfg(target_vendor)` attribute.][57465] E.g.
  `#[cfg(target_vendor="apple")] fn main() { println!("Hello Apple!"); }`
- [Integer patterns such as in a match expression can now be exhaustive.][56362]
  E.g. You can have match statement on a `u8` that covers `0..=255` and
  you would no longer be required to have a `_ => unreachable!()` case.
- [You can now have multiple patterns in `if let` and `while let`
  expressions.][57532] You can do this with the same syntax as a `match`
  expression. E.g.
  ```rust
  enum Creature {
      Crab(String),
      Lobster(String),
      Person(String),
  }

  fn main() {
      let state = Creature::Crab("Ferris");

      if let Creature::Crab(name) | Creature::Person(name) = state {
          println!("This creature's name is: {}", name);
      }
  }
  ```
- [You can now have irrefutable `if let` and `while let` patterns.][57535]
  Using this feature will by default produce a warning as this behaviour
  can be unintuitive. E.g. `if let _ = 5 {}`
- [You can now use `let` bindings, assignments, expression statements,
  and irrefutable pattern destructuring in const functions.][57175]
- [You can now call unsafe const functions.][57067] E.g.
  ```rust
  const unsafe fn foo() -> i32 { 5 }
  const fn bar() -> i32 {
      unsafe { foo() }
  }
  ```
- [You can now specify multiple attributes in a `cfg_attr` attribute.][57332]
  E.g. `#[cfg_attr(all(), must_use, optimize)]`
- [You can now specify a specific alignment with the `#[repr(packed)]`
  attribute.][57049] E.g. `#[repr(packed(2))] struct Foo(i16, i32);` is a
  struct with an alignment of 2 bytes and a size of 6 bytes.
- [You can now import an item from a module as an `_`.][56303] This allows you
  to import a trait's impls, and not have the name in the namespace. E.g.
  ```rust
  use std::io::Read as _;

  // Allowed as there is only one `Read` in the module.
  pub trait Read {}
  ```
- [You may now use `Rc`, `Arc`, and `Pin` as method receivers][56805].

Compiler
--------
- [You can now set a linker flavor for `rustc` with the `-Clinker-flavor`
  command line argument.][56351]
- [The mininum required LLVM version has been bumped to 6.0.][56642]
- [Added support for the PowerPC64 architecture on FreeBSD.][57615]
- [The `x86_64-fortanix-unknown-sgx` target support has been upgraded to
  tier 2 support.][57130] Visit the [platform support][platform-support]
  page for information on Rust's platform support.
- [Added support for the `thumbv7neon-linux-androideabi` and
  `thumbv7neon-unknown-linux-gnueabihf` targets.][56947]
- [Added support for the `x86_64-unknown-uefi` target.][56769]

Libraries
---------
- [The methods `overflowing_{add, sub, mul, shl, shr}` are now `const`
  functions for all numeric types.][57566]
- [The methods `rotate_left`, `rotate_right`, and `wrapping_{add, sub, mul,
  shl, shr}`
  are now `const` functions for all numeric types.][57105]
- [The methods `is_positive` and `is_negative` are now `const` functions for
  all signed numeric types.][57105]
- [The `get` method for all `NonZero` types is now `const`.][57167]
- [The methods `count_ones`, `count_zeros`, `leading_zeros`, `trailing_zeros`,
  `swap_bytes`, `from_be`, `from_le`, `to_be`, `to_le` are now `const` for all
  numeric types.][57234]
- [`Ipv4Addr::new` is now a `const` function][57234]

Stabilized APIs
---------------
- [`unix::FileExt::read_exact_at`]
- [`unix::FileExt::write_all_at`]
- [`Option::transpose`]
- [`Result::transpose`]
- [`convert::identity`]
- [`pin::Pin`]
- [`marker::Unpin`]
- [`marker::PhantomPinned`]
- [`Vec::resize_with`]
- [`VecDeque::resize_with`]
- [`Duration::as_millis`]
- [`Duration::as_micros`]
- [`Duration::as_nanos`]


Cargo
-----
- [Cargo should now rebuild a crate if a file was modified during the initial
  build.][cargo/6484]

Compatibility Notes
-------------------
- The methods `str::{trim_left, trim_right, trim_left_matches,
  trim_right_matches}` are now deprecated in the standard library, and their
  usage will now produce a warning.  Please use the `str::{trim_start,
  trim_end, trim_start_matches, trim_end_matches}` methods instead.
- The `Error::cause` method has been deprecated in favor of `Error::source`
  which supports downcasting.
