Finally, we have all the elements we need to implement a mini version of ls command in Rust. Function main delegates to run. We do this in order to catch any errors and display a more user-friendly error message: fn main() { match run() { ...
In this post, we work on the code that reads the contents of a directory. First, we get the path of the directory from a command line argument: let args: Vec<String> = env::args().collect(); if args.len() < 2 { eprintln!("Usage: readd...
In this installment on our road to implementing a mini version of ls in Rust, we are going to get information about one file: Is it a regular file or a directory? File permissions Time of last modification Number of hard links That is the kind ...
This post is the first in a series that will develop a small rewrite of ls command with a small subset of features of the official Linux ls command. For a Rust implementation of ls that aspires to implement the full rewrite, take a look at coreutils....
The topic of today's post is opening and reading text files. Simple stuff, and something that you can find described on countless pages, including Rust's official documentation. I am doing this one for my record. Reading the whole file with one funct...
This is something about Rust I find fascinating. It is about how the compiler manages to do the right thing. I'll explain what I mean, but first we have to prepare the scene. We will create a structure and implement Drop trait for it. Here's the stru...
