Syntax error Path Struct in Rust Programming

Path Struct in Rust Programming

Path struct in Rust is used to represent the file paths in the underlying filesystem. It should also be noted that a Path in Rust is not represented as a UTF-8 string; instead, it is stored as a vector of bytes (Vec<u8>).

Example

Consider the example shown below −

 Live Demo

use std::path::Path;

fn main() {
   // Create a `Path` from an `&'static str`
   let path = Path::new(".");
   // The `display` method returns a `Show`able structure
   let display = path.display();
   // Check if the path exists
   if path.exists() {
      println!("{} exists", display);
   }
   // Check if the path is a file
   if path.is_file() {
      println!("{} is a file", display);
   }
   // Check if the path is a directory
   if path.is_dir() {
      println!("{} is a directory", display);
   }
   // `join` merges a path with a byte container using the OS specific
   // separator, and returns the new path
   let new_path = path.join("a").join("b");
   // Convert the path into a string slice
   match new_path.to_str() {
      None => panic!("new path is not a valid UTF-8 sequence"),
      Some(s) => println!("new path is {}", s),
   }
}

Output 

If we run the above code, we will see the following output −

. exists
. is a directory
new path is ./a/b
