Rust 1.26 版本发布，系统编程语言

Rust 1.26 版本发布。Rust 是一门由 Mozilla 开发的专注于安全性，速度和并发性的系统编程语言。主要更新内容如下：

语言

• 现在 Closures 实现了 Copy and/or Clone

• Inclusive range 语法，如 for x in 0..=10 现可用

• Stablise '_ . The underscore lifetime can be used anywhere where a lifetime can be elided.

• impl Trait is now stable allowing you to have abstract types in returns or in function parameters. e.g.  fn foo() -> impl Iterator<Item=u8> or  fn open(path: impl AsRef<Path>) .

• Pattern matching will now automatically apply dereferences.

• 128-bit integers in the form of u128 and  i128 are now stable.

• main can now return  Result<(), E: Debug> in addition to  () .

• A lot of operations are now available in a const context. E.g. You can now index into constant arrays, reference and dereference into constants, and use Tuple struct constructors.
