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 −
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
