how_to_rust

"I know how to do this in Typescript. But how do I do it in Rust?"

This repo contains programs that describe how to do stuff in Rust that you know how to do in another language like TypeScript.

First, some basics

Install Rust using rustup by following the instruction at https://www.rust-lang.org

Create, compile, run

touch hello.rs
echo "fn main() { println!(\"Hello computer\") }" > hello.rs
rustc hello.rs
./hello

Create project with cargo

mkdir project_name
cd project_name
cargo init

Compile with cargo

cargo run

# or

cargo build
./target/debug/project_name
cargo build --release
./target/release/project_name

This repo contains a CLI application that you can use to run some of the examples:

cargo run <example_file_name>

# or

cargo build
./target/debug/how_to_rust <example_file_name>

Some of the examples just contain tests which can be run like so:

cargo test
