rust-examples

Some examples of snippets I use a lot. Helped me get started and hope it will help others as well.

Installing Rust

1. Run curl https://sh.rustup.rs -sSf | sh

2. then make sure Cargo is in your path by adding this to your profile: export PATH="$HOME/.cargo/bin:$PATH". I use oh-my-zsh so I just do nano ~/.zshrc then add that line to the bottom via CTRL + W and then CTRL + V to get to the bottom quickly, or you could just echo it to .zshrc via echo 'export PATH="$HOME/.cargo/bin:$PATH"' >> ~/.zshrc.

Running using cargo build

virtual manifest method

From the root folder simply run cargo build and it will build every sub directory package. Then explicitly run with -p the specific package you want to run, e.g., cargo run -p tcp_server.

Manual method

For each folder, cd into the folder and run cargo build then cargo run and it should work fine.

Examples

below are the examples in each subfolder under the main repo

tcp_server

Starts a local server on port 9123.

You can quickly netcat a message to it and it should respond back like this:

echo 1 | netcat localhost 9123

input_output

A simple example where it asks for a number input and it prints out the number you selected.
