rust-doc - Rust systems programming language - Documentation

Overview
Dependencies
Rust is a curly-brace, block-structured expression language. It visually resembles the C language family, but differs significantly in syntactic and semantic details. Its design is oriented toward concerns of "programming in the large", that is, of creating and maintaining boundaries - both abstract and operational - that preserve large-system integrity, availability and concurrency.
It supports a mixture of imperative procedural, concurrent actor, object-oriented and pure functional styles. Rust also supports generic programming and meta-programming, in both static and dynamic styles.
This package contains the Rust tutorial, language reference and standard library documentation.

OpenSUSE Tumbleweed oss: Updated from 1.36.0-1.1 to 1.37.0-1.1

Sep 05
  • Update to version 1.37.0
    • Language
    • #[must_use] will now warn if the type is contained in a tuple, Box, or an array and unused.
    • You can now use the `cfg` and `cfg_attr` attributes on generic parameters.
    • You can now use enum variants through type alias. e.g. You can write the following:
      ```
      type MyOption = Option<u8>;
      fn increment_or_zero(x: MyOption) -> u8 {
      match x {
      MyOption::Some(y) => y + 1,
      MyOption::None => 0,
      }
      }
      ```
    • You can now use `_` as an identifier for consts. e.g. You can write `const _: u32 = 5;`.
    • You can now use `#[repr(align(X)]` on enums.
    • The `?` Kleene macro operator is now available in the 2015 edition.
    • Compiler
    • You can now enable Profile-Guided Optimization with the `-C profile-generate` and `-C profile-use` flags. For more information on how to use profile guided optimization, please refer to the rustc book.
    • The `rust-lldb` wrapper script should now work again.
    • Libraries
    • `mem::MaybeUninit<T>` is now ABI-compatible with `T`.
    • Stabilized APIs
    • BufReader::buffer
    • BufWriter::buffer
    • Cell::from_mut
    • Cell<[T]>::as_slice_of_cells
    • Cell<slice>::as_slice_of_cells
    • DoubleEndedIterator::nth_back
    • Option::xor
    • Wrapping::reverse_bits
    • i128::reverse_bits
    • i16::reverse_bits
    • i32::reverse_bits
    • i64::reverse_bits
    • i8::reverse_bits
    • isize::reverse_bits
    • slice::copy_within
    • u128::reverse_bits
    • u16::reverse_bits
    • u32::reverse_bits
    • u64::reverse_bits
    • u8::reverse_bits
    • usize::reverse_bits
    • Cargo
    • Cargo.lock files are now included by default when publishing executable crates with executables.
    • You can now specify `default-run="foo"` in `[package]` to specify the default executable to use for `cargo run`.
    • cargo-vendor is now provided as a sub-command of cargo
    • Compatibility Notes
    • Using `...` for inclusive range patterns will now warn by default. Please transition your code to using the `..=` syntax for inclusive ranges instead.
    • Using a trait object without the `dyn` will now warn by default. Please transition your code to use `dyn Trait` for trait objects instead.
