Rust 1.22.0 已发布，该版本带来了语言、编译器、库和稳定 API 方面的更新，具体如下： Language non_snake_case lint now allows extern no-mangle functions Now accepts underscores in unicode escapes T op= &T now works for numeric types. eg. let mut x = 2; x += &8; types that impl Drop are now allowed in const and static types Compiler rustc now defaults to having 16 codegen units at debug on supported platforms. rustc will no longer inline in codegen units when compiling for debug This should decrease compile times for debug builds. strict memory alignment now enabled on ARMv6 Remove support for the PNaCl target le32-unknown-nacl Libraries Allow atomic operations up to 32 bits on armv5te_unknown_linux_gnueabi Box<Error> now impls From<Cow<str>> std::mem:iscriminant is now guaranteed to be Send + Sync fs::copy now returns the length of the main stream on NTFS. Properly detect overflow in Instant += Duration. impl Hasher for {&mut Hasher, Box<Hasher>} impl fmt:ebug for SplitWhitespace. Option<T> now impls Try This allows for using ? with Option types. Stabilized APIs Cargo Cargo will now build multi file examples in subdirectories of the examples folder that have a main.rs file. Changed [root] to [package] in Cargo.lock Packages with the old format will continue to work and can be updated with cargo update. Now supports vendoring git repositories Misc libbacktrace is now available on Apple platforms. Stabilised the compile_fail attribute for code fences in doc-comments. This now lets you specify that a given code example will fail to compile. Compatibility Notes The minimum Android version that rustc can build for has been bumped to 4.0 from 2.3 Allowing T op= &T for numeric types has broken some type inference cases 更多更新内容点此查阅 下载地址 Source code (zip) Source code (tar.gz) https://www.rust-lang.org/en-US/install.html Rust 是一种系统编程语言。 它有着惊人的运行速度，能够防止段错误，并保证线程安全。 Rust 1.22.0 发布，Mozilla 开发的系统编程语言下载地址
