其中最简单的rustc一个直接生成一个静态库,而Clang进行链接,如下所示: # Compile the Rust static library, called "xyz" rustc --crate-type=staticlib -O -C linker-plugin-lto -o libxyz.a lib.rs # Compile the C code with "-flto" clang -flto -c -O2 main.c # Link everything clang -...

(6)集合类型:LinkList<T>、VecQueue<T>、BTreeSet<T>、BTreeMap<T>等。 03 STD库 STD库建立在OS的系统调用(SYSCALL)基础上,只适用于用户态编程。 STD库最主要的工作是针对OS资源设计Rust的类型、Trait及函数。 STD库的主要内容如下。 (1)对CORE库及ALLOC库的内容进行映射。
