Rust by Example

The Path struct represents file paths in the underlying filesystem. There are two flavors of Path: posix::Path, for UNIX-like systems, and windows::Path, for Windows. The prelude exports the appropriate platform-specific Path variant.

A Path can be created from an OsStr, and provides several methods to get information from the file/directory the path points to.

Note that a Path is not internally represented as an UTF-8 string, but instead is stored as a vector of bytes (Vec). Therefore, converting a Path to a &str is not free and may fail (an Option is returned).

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();

// `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),

}

}

Be sure to check at other Path methods (posix::Path or windows::Path) and the Metadata struct.
