Rust 1.24.0 发布，Mozilla 开发的系统编程语言

Linuxeden 开源社区 --

Rust 1.24.0 发布了。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。

更新内容：

语言

• External sysv64 ffi is now available. eg. extern "sysv64" fn foo () {}

编译器

• rustc now uses 16 codegen units by default for release builds. For the fastest builds, utilize codegen-units=1.
• Added armv4t-unknown-linux-gnueabi target.
• Add aarch64-unknown-openbsd support

库

• str::find::<char> now uses memchr. This should lead to a 10x improvement in performance in the majority of cases.
• OsStr‘s Debug implementation is now lossless and consistent with Windows.
• time::{SystemTime, Instant} now implement Hash.
• impl From<bool> for AtomicBool
• impl From<{CString, &CStr}> for {Arc<CStr>, Rc<CStr>}
• impl From<{OsString, &OsStr}> for {Arc<OsStr>, Rc<OsStr>}
• impl From<{PathBuf, &Path}> for {Arc<Path>, Rc<Path>}
• float::from_bits now just uses transmute. This provides some optimisations from LLVM.
• Copied AsciiExt methods onto char
• Remove T: Sized requirement on ptr::is_null()
• impl From<RecvError> for {TryRecvError, RecvTimeoutError}
• Optimised f32::{min, max} to generate more efficent x86 assembly
• [u8]::contains now uses memchr which provides a 3x speed improvement
