Rust PathBuf Examples

These are examples of the functions and features available in Rusts PathBuf

This is a work in progress making examples from > this page > https : //doc.rust - lang.org/std/path/struct.PathBuf.html#method.display >

Pop

rust

use std::path::PathBuf;

fn main() {
    let mut path = PathBuf::from("/Users/alan/Desktop/alfa.v1.txt");
    path.pop();
    dbg! {path};
}

results full

NOTE : the pop just returns true not the item that was popped as far as I can tell

Set Extension

rust

fn main() {
    let mut path = PathBuf::from("/Users/alan/Desktop/alfa.v1.txt");
    path.set_extension("neo");
    dbg! {path};
}

Set File Name

rust

fn main() {
    let mut path = PathBuf::from("/Users/alan/Desktop/bravo.v2.txt");
    path.set_file_name("bravo.v2.txt");
    dbg! {path};
}

results full

Ancestors

rust

fn main() {
    let path = PathBuf::from("/Users/alan/Desktop/alfa.v1.txt");
    let ancestors = path.ancestors();
    ancestors.for_each(|x| println!("{}", x.display()));
}

Canonicalize

rust

fn main() {
    let mut path = PathBuf::from("/Users/alan/Desktop/subdir/../alfa.v1.txt");
    path = path.canonicalize().unwrap();
    dbg! {path};
}

results full

Components

rust

fn main() {
    let path = PathBuf::from("/Users/alan/Desktop/alfa.v1.txt");
    let components = path.components();
    dbg! {components};
}

results full

Display Name

rust

fn main() {
    let path = PathBuf::from("/Users/alan/Desktop/alfa.v1.txt");
    let display_name = path.display();
    dbg! {display_name};
}

results full

Extension

rust

fn main() {
    let path = PathBuf::from("/Users/alan/Desktop/alfa.v1.txt");
    let extension = path.extension().unwrap();
    dbg! {extension};
}

results full

File Name

rust

fn main() {
    let path = PathBuf::from("/Users/alan/Desktop/alfa.v1.txt");
    let file_name = path.file_name().unwrap();
    dbg! {file_name};
}

File Stem

(There's a [TODO: Code shorthand span ] that's in nightly as well that will do a similar thing as thise but return [TODO: Code shorthand span ] instead)

rust

fn main() {
    let path = PathBuf::from("/Users/alan/Desktop/alfa.v1.txt");
    let file_stem = path.file_stem().unwrap();
    dbg! {file_stem};
}

Join Paths

This creates a new path from the joined parts

rust

fn main() {
    let path = PathBuf::from("/Users/alan/Desktop");
    let joined_path = path.join("alfa.v1.txt");
    dbg! {joined_path};
}

results full

Metadata

rust

fn main() {
    let path = PathBuf::from("/Users/alan/Desktop/alfa.v1.txt");
    let metadata = path.metadata().unwrap();
    dbg! {metadata};
}

results full

Parent

rust

fn main() {
    let path = PathBuf::from("/Users/alan/Desktop/alfa.v1.txt");
    let parent = path.parent().unwrap();
    dbg! {parent};
}

results full

Strip Prefix

rust

fn main() {
    let path = PathBuf::from("/Users/alan/Desktop/alfa.v1.txt");
    let prefix_removed = path.strip_prefix("/Users/alan/").unwrap();
    dbg! {prefix_removed};
}
