A simple library to read/write files more easily in Rust.
match fstream::write_text("test_file.txt", "Hello world!", true) {
Some(b) => println!("Number of bytes written to the file: {}", b),
None => println!("Couldn't open or write to the file!"),
}or just:
fstream::write_text("test_file.txt", "Hello world!", true).unwrap();match fstream::read_text("test_file.txt") {
Some(s) => println!("File content: {}", s),
None => println!("Couldn't open or read the file"),
}or just:
