contexts can customize the implementation of standard algorithms for optimal performance. ● Key Features: ● Combining scheduler and policy. ● Minimal, incremental API changes.Combining Scheduler with and 4 are likely to make C++26. 2 and 3 will be beyond C++ 26. These are just some of the likely features that have progressed sufficiently and fit in a talk format, though they still may enter the standard

Leveraging C++20/23 Features for Low Level InteractionsOverview In a baremetal environment, we’re going to demonstrate e�ective use of C++ How did we end up with C language HW interactions? What are best e�ectively in line with C++ best practices? �. See also Stroustrup (2023), in referencesKey C++ Safety Features There’s lots, but….

管理安装多个官方版本的 Rust 二进制程序。 2.配置基于目录的 Rust 工具链。 3.安装和更新来自 Rust 的发布通道: nightly, beta 和 stable。 4.接收来自发布通道更新的通知。 5.从官方安装历史版本的 nightly 工具链。 6.通过指定 stable 版本来安装。 7.安装额外的 std 用于交叉编译。 8.安装自定义的工具链。 rustup ，它里 面会含有一些元数据供编译器使用，最终会静态链接到目标文件之中。 例#![crate_type = "dylib"]。  feature - 可以开启一些不稳定特性，只可在 nightly 版的编译器中使用。  no_builtins - 去掉内建函数。  no_main- 不生成 main 这个符号，当你需要链接的库中已经定义了 main 函数时 会用到。  debug-assertions = true codegen-units = 1 5.2.4 feature 段落 [features]段落中的字段被用于条件编译选项或者是可选依赖。例如： [package] name = "awesome" [features] # 此字段设置了可选依赖的默认选择列表， # 注意这里的"session"并非一个软件包名称， # 而是另一个 featrue

talk results in the improvement of Rust for everyone! Introduction Language Library Tooling Nightly features A general priority is to stabilize them (or to find alternatives): https://github.com/Rus RUSTC_BOOTSTRAP. The rest of this talk focuses on things that are not in nightly. Language Library Tooling Nightly features cfg(no_fp_fmt_parse) cfg(no_global_oom_handling) cfg(no_rc) cfg(no_sync) Language Library Modularization of core and alloc The kernel does not need a range of core/alloc features. Configuring them off is important for correctness, code size… Likely useful for other domains
