Generics和Trait粗看起来是zero cost abstraction的编译时多态(compile-time polymorphism),类似于C++中的template和C++17里的Concept。但实际上它设计的精巧已经远不是C++中template的同类了。其中一点就是统一了compile-time和run-time polymorphism,编译时多态叫trait,运行时多态叫trait object,省去了不少程序语义方面的...

首先,内核和设备驱动程序是用 Rust 编写的,Rust 是一种提供 compile-time 内存安全、类型安全和严格别名的系统编程语言。Tock 使用 Rust 来保护内核(例如调度程序和硬件抽象层)不受特定于平台的设备驱动程序的影响,并将设备驱动程序彼此隔离。其次,Tock 使用内存保护单元将应用程序彼此和内核隔离开来。 Google 发布的...

Compilation结构体中的字段包括config、build_config、cx、source_map、packages、targets等。这些字段包含了与编译相关的信息,如配置信息、构建配置、源文件路径映射、待编译的包列表、目标文件等。Compilation结构体还包含了与编译过程相关的方法,如compile_test、doctest、compile、build_unit等。
