Rust cheatsheet
August 6, 2020

I start to learn Rust programming language. This is a post where I collect tips and tricks about Rust

This post will be updated (I hope often :)

how to loop backwards with for loop
for z in (0..100).rev(){
  println!("{:?}", z);
is even
x & 1 == 1;
concatenate vectors
let mut a = vec![1, 2, 3];
let mut b = vec![4, 5, 6];
a.append(&mut b);
remove all duplicates from vector
let mut v = vec![1,3,10,2,5,3,6,1,8]
//sort is the key
v.dedup(); //[1,2,3,5,6,8,10] 
PathBuff to String
// let assume that path is PathBuff
  // we need into_os_string step because String is UTF-8 encoded,
  // but PathBuff might not be. For example on Windows
