Rust 1.69.0 稳定版已[发布][Link 1]。

### **1.69.0 稳定版中有什么** ###

**Cargo 建议自动修复警告**

Rust 1.29.0 添加了 cargo fix 子命令来自动修复一些简单的编译器警告。从那时起，可以自动修复的警告数量继续稳步增加。此外，还增加了对自动修复一些简单的 Clippy 警告的支持。

在 1.69.0 版本中，Cargo 会建议在检测到可自动修复的警告时运行 cargo fix 或 cargo clippy --fix ：

warning: unused import: `std:#⃣:Hash`
     --> src/main.rs:1:5
      |
    1 | use std:#⃣:Hash;
      |     ^^^^^^^^^^^^^^^
      |
      = note: `#[warn(unused_imports)]` on by default
    
    warning: `foo` (bin "foo") generated 1 warning (run `cargo fix --bin "foo"` to apply 1 suggestion)

注意，上面显示的完整 Cargo 调用仅在您想要精确地将修复应用到单个 crate 时才有必要。如果想对工作区的所有默认成员应用修复，那么一个简单的 `cargo fix` （无需附加参数）就足够了。

**默认情况下，调试信息不再包含在构建脚本中**

为了提高编译速度，Cargo 现在默认避免在构建脚本中发出调试信息。构建脚本成功执行时不会有可见的效果，但构建脚本中的回溯将包含较少的信息。

如果要调试构建脚本，可以将此代码段添加到 `Cargo.toml` 以再次发出调试信息：

[profile.dev.build-override]
    debug = true
    [profile.release.build-override]
    debug = true

#### **稳定的 API** ####

*  [CStr::from\_bytes\_until\_nul][CStr_from_bytes_until_nul]
 *  [core::ffi::FromBytesUntilNulError][core_ffi_FromBytesUntilNulError]

这些 API 现在在 const 上下文中是稳定的：

*  [SocketAddr::new][SocketAddr_new]
 *  [SocketAddr::ip][SocketAddr_ip]
 *  [SocketAddr::port][SocketAddr_port]
 *  [SocketAddr::is\_ipv4][SocketAddr_is_ipv4]
 *  [SocketAddr::is\_ipv6][SocketAddr_is_ipv6]
 *  [SocketAddrV4::new][SocketAddrV4_new]
 *  [SocketAddrV4::ip][SocketAddrV4_ip]
 *  [SocketAddrV4::port][SocketAddrV4_port]
 *  [SocketAddrV6::new][SocketAddrV6_new]
 *  [SocketAddrV6::ip][SocketAddrV6_ip]
 *  [SocketAddrV6::port][SocketAddrV6_port]
 *  [SocketAddrV6::flowinfo][SocketAddrV6_flowinfo]
 *  [SocketAddrV6::scope\_id][SocketAddrV6_scope_id]
