Getting the absolute path from a PathBuf

Question

Given a relative path:

PathBuf::from("./cargo_home") 

Is there a way to get the absolute path?

Answer 1

Rust 1.5.0 added std::fs::canonicalize, which sounds pretty close to what you want:

Returns the canonical form of a path with all intermediate components normalized and symbolic links resolved.

Note that, unlike the accepted answer, this removes the ./ from the returned path.

A simple example from my machine:

use std::fs; use std::path::PathBuf;  fn main() {     let srcdir = PathBuf::from("./src");     println!("{:?}", fs::canonicalize(&srcdir));      let solardir = PathBuf::from("./../solarized/.");     println!("{:?}", fs::canonicalize(&solardir)); }
