How to read a file into a buffer in Rust?

@cassandra  You can use the std::fs::read() function to read the contents of a file into a buffer in Rust. Here's an example of how you can use this function to read the contents of a file into a variable of type Vec<u8>:

use std::fs;

fn main() {
  let file_name = "path/to/file.txt";
  let file_contents = fs::read(file_name).expect("Failed to read file");
}

@cassandra  you can use std::io::Read trait to read the contents of a file into a buffer, here's an example of how you can use this trait to read the contents of a file into a variable of type Vec<u8>

use std::fs::File;
use std::io::Read;

fn main() {
  let file_name = "path/to/file.txt";
  let mut file = File::open(file_name).expect("Failed to open file");
  let mut file_contents = Vec::new();
  file.read_to_end(&mut file_contents).expect("Failed to read file");
}

This will open the file, read it's contents into a buffer and return the number of bytes read.
