Recently, I just learnt Rust and using it to write a simple youtube downloader with reference from node-ytdl . In this blog, I would like to share the code and how did I make it. You can find the full source code here . Install development environment I am using Windows 10 and scoop package manager. Therefore, I use the following commands. Run scoop install rustup-msvc to install rustup . Run setx "%path%;%USERPROFILE%\\scoop\\persist\\rustup\\.cargo\\bin" to add rustup to the path. Restart termial (git-bash in my case) and check the installation with rustup --version; rustc --version; cargo --version Export custom RUST_HOME : export RUSTUP_HOME=$HOME/scoop/persist/rustup/.cargo/bin/rustup Install a toolchain for rustup : rustup toolchain install stable-x86_64-pc-windows-msvc Setup project Run cargo new simple_rust_youtube_downloader --bin && cd simple_rust_youtube_downloader to create and navigate to the project. Add these dependencies to ...
