Rust Cheat Sheet

Variables & Mutability

Variables are immutable by default. This makes Rust safer and makes concurrency easier.
Immutable means once a value is bound to that variable, it cannot be changed.
For example:

fn main() {
 let x = 5;

A curated list of command-line utilities written in Rust

Note: I have moved this list to a proper repository. I'll leave this gist up, but it won't be updated. To submit an idea, open a PR on the repo.

Note that I have not tried all of these personally, and cannot and do not vouch for all of the tools listed here. In most cases, the descriptions here are copied directly from their code repos. Some may have been abandoned. Investigate before installing/using.

The ones I use regularly include: bat, dust, fd, fend, hyperfine, miniserve, ripgrep, just, cargo-audit and cargo-wipe.

• atuin: "Magical shell history"
• bandwhich: Terminal bandwidth utilization tool

//v1.4: Adding option for including a header for each DNP day to fold

//'first' will add to top of file. 'last' will add to bottom of file
let firstOrLastLine = 'first';

//Name of the Quick Capture file. Do NOT include extension '.md'
let qcFileName = 'Quick Capture';

//Leave this blank if you want to use the default file path location (set to '/' to use root of vault)

data "rancher2_cluster_template" "hardened" {
    name = "hardened-template"
}

or create a new RKE cluster template:

Kubernetes v1.16 API deprecation testing

Examples of how to test the impact of the v1.16 API deprecations and ways to debug early!

If this is the first time you're hearing of these deprecations STOP and read this blog post (thanks @vllry!).

Common misunderstandings

1. The exact apiVersion: value that I use in my manifest is stored on disk (etcd).
