File: rust/compiler/rustc_index/src/idx.rs 在Rust的源代码中,idx.rs文件位于rust/compiler/rustc_index/src/目录下,它定义了用于索引访问的Idx trait。以下是该文件的详细介绍: Idx是一个基本的整数索引类型,它用于支持Rust编译器(rustc)中的各种索引访问操作。Idx trait允许实现它的类型在索引访问中扮演特定...
File: rust/compiler/rustc_target/src/json.rs 在Rust源代码中,rust/compiler/rustc_target/src/json.rs文件的作用是定义了一系列与JSON格式相关的结构体以及相关的trait实现。 该文件中定义了Json结构体,它可以表示一个JSON值,可以是null、布尔值、整数、浮点数、字符串、数组或对象。Json结构体的from_str方法...
在Rust源代码中的rust/compiler/rustc_target/src/abi/call/mips.rs文件是关于MIPS架构的函数调用ABI(Aplication Binary Interface)定义。ABI是编程语言与底层平台之间的接口规范,用于定义函数调用、参数传递和异常处理等细节。
A library forCargo build scriptsto compile a set of C/C++/assembly/CUDA files into a static archive for Cargo to link into the crate being built. This crate does not compile code itself; it calls out to the default compiler for the platform. This crate will automatically detect situations ...
While it's possible to use the Rust compiler (rustc) directly to build crates, most projects use the Rust build tool and dependency manager called Cargo.Cargo does lots of things for you, including:Create new project templates with the cargo new command. Build a project with the cargo ...
By design, our paired code generators work together to control both sides of the FFI boundary. Ordinarily in Rust writing your ownextern "C"blocks is unsafe because the Rust compiler has no way to know whether the signatures you've written actually match the signatures implemented in the other...
One could use std::os::raw::c_void if they want to support old Rust compiler down to 1.1.0. After Rust 1.30.0, it was re-exported by this definition. For more information, please read RFC 2521. Equivalent to C's char type. C's char type is completely unlike Rust's char type;...
These features set Rust apart from low-level languages like C and C++.Rust also offers the following advantages that make it a great fit for a wide range of applications:Type safe: The compiler assures that no operation will be applied to a variable of a wrong type. Memory safe: Rust ...
Given that you've installed Rust, you will have access to the compilerrustc, an executable you use via the command line. Create a filemain.rs Give it the following content: fnmain(){println!("Hello world");} Compile program withrustc ...
Compile program withrustc , you defined an entry point to the application a methodmain(). This is you telling Rust where to start the program execution. You used the keywordfnto define a function, followed by the function name \"main\" and curly braces: ...
