preface

Rust’s learning curve is steep enough that it can be difficult even for systems programmers. But Rust has the best support for WebAssembly, so for Web programmers, you can rewrite CPU-intensive JavaScript logic in Rust and run it in WebAssembly, and the combination of JavaScript and Rust will give you control over everything.

This tutorial is not intended to be exhaustive, but you should have some experience with Node.js, and you’ll see comparisons of JavaScript, TypeScript, and Rust to help you understand.

The body of the

In the Node.js world, we use NVM or NVM-Windows to seamlessly install and switch between different versions of Node.js. The counterpart in the Rust world is Rustup

Rustup manages Rust installations and additional build targets such as WebAssembly, in addition to core tools such as Cargo (NPM for Rust), Clippy (ESLint for Rust), and RustFMT (Prettier for Rust). Before using Rust, we first install Rustup[install connection]. After installing Rustup, we see the following results when we execute Rustup:

$ rustup
rustup 1.24.3 (ce5817a94 2021- 05- 31)
The Rust toolchain installer

USAGE:
    rustup [FLAGS] [+toolchain] <SUBCOMMAND>

FLAGS:
    -v, --verbose    Enable verbose output
    -q, --quiet      Disable progress output
    -h, --help       Prints help information
    -V, --version    Prints version information

ARGS:
    <+toolchain>    release channel (e.g. +stable) or custom toolchain to set override

SUBCOMMANDS:
    show           Show the active and installed toolchains or profiles
    update         Update Rust toolchains and rustup
    check          Check for updates to Rust toolchains and rustup
    default        Set the default toolchain
    toolchain      Modify or query the installed toolchains
    target         Modify a toolchain's supported targets component Modify a toolchain's installed components
    override       Modify directory toolchain overrides
    run            Run a command with an environment configured for a given toolchain
    which          Display which binary will be run for a given command
    doc            Open the documentation for the current toolchain
    man            View the man page for a given command
    self           Modify the rustup installation
    set            Alter rustup settings
    completions    Generate tab-completion scripts for your shell
    help           Prints this message or the help of the given subcommand(s)

DISCUSSION:
    Rustup installs The Rust Programming Language from the official
    release channels, enabling you to easily switch between stable,
    beta, and nightly compilers and keep them updated. It makes
    cross-compiling simpler with binary builds of the standard library
    for common platforms.

    If you are new to Rust consider running `rustup doc --book` to
    learn Rust.
Copy the code

By default, Rustup installs the latest versions of Rust and Cargo:

$cargo -- Version Cargo 1.6.0 (4ED5D137B 2021-10-04) $cargo -- Version Cargo 1.6.0 (4ED5D137B 2021-10-04)Copy the code
