Trait rpf::PathMod [−] [src]

pub trait PathMod {
    fn is_dot(&self) -> bool;
    fn last_component(&self) -> Option<PathBuf>;
    fn first_component(&self) -> Option<PathBuf>;
    fn as_str(&self) -> &str;
    fn as_string(&self) -> String;
}

Adds some useful functions for manipulating and retrieving information from paths

Required Methods

Returns true if the path's file name starts with a "."

Example

use rpf::PathMod;
use std::path::Path;

let path = Path::new("/test/dot/.dotfile");
assert_eq!(path.is_dot(), true);

Returns a PathBuf of &self's last component

Example

use rpf::PathMod;
use std::path::PathBuf;

let path = PathBuf::from("/tmp/test/mod");
let last = path.last_component().unwrap();
assert_eq!(last, PathBuf::from("mod"));

Returns a PathBuf of &self's first component

Example

use rpf::PathMod;
use std::path::PathBuf;

let path = PathBuf::from("/tmp/test/mod");
let first = path.first_component().unwrap();
assert_eq!(first, PathBuf::from("/"));

Returns a &str for a path, returns a blank string if unable to get a string for the path

Example

use rpf::PathMod;
use std::path::PathBuf;

let path = PathBuf::from("/usr/share");
let path_str = &path.as_str();
assert_eq!(path_str, &"/usr/share");

Returns a String for a path, returns an empty string if unable to get a string for a path

Example

use rpf::PathMod;
use std::path::PathBuf;

let path_string = PathBuf::from("/var/log/test").as_string();
assert_eq!(path_string, "/var/log/test".to_string());
