Copies a file from one location to another.

Arguments

• from - The source file path (can be a &str, String, Path, or std::path::PathBuf).

// Copy 'Cargo.toml' to 'folder/Cargo_new_1.toml'.
let from: &str = "Cargo.toml";
let to: &str = "folder/Cargo_new_1.toml";
copy_file(from, to);

Using Path references

use file_io::copy_file;
use std::path::Path;

// Copy 'Cargo.toml' to 'folder/Cargo_new_2.toml'.
let from: &Path = Path::new("Cargo.toml");
let to: &Path = Path::new("folder/Cargo_new_2.toml");
copy_file(from, to);
