Function std::old_io::fs::readdirUnstable

pub fn readdir(path: &Path) -> IoResult<Vec<Path>>

Retrieve a vector containing all entries within a provided directory

Example

fn main() { use std::old_io::fs::PathExtensions; use std::old_io::fs; use std::old_io; // one possible implementation of fs::walk_dir only visiting files fn visit_dirs<F>(dir: &Path, cb: &mut F) -> old_io::IoResult<()> where F: FnMut(&Path), { if dir.is_dir() { let contents = try!(fs::readdir(dir)); for entry in contents.iter() { if entry.is_dir() { try!(visit_dirs(entry, cb)); } else { (*cb)(entry); } } Ok(()) } else { Err(old_io::standard_error(old_io::InvalidInput)) } } }

use std::old_io::fs::PathExtensions;
use std::old_io::fs;
use std::old_io;

// one possible implementation of fs::walk_dir only visiting files
fn visit_dirs<F>(dir: &Path, cb: &mut F) -> old_io::IoResult<()> where
    F: FnMut(&Path),
{
    if dir.is_dir() {
        let contents = try!(fs::readdir(dir));
        for entry in contents.iter() {
            if entry.is_dir() {
                try!(visit_dirs(entry, cb));
            } else {
                (*cb)(entry);
            }
        }
        Ok(())
    } else {
        Err(old_io::standard_error(old_io::InvalidInput))
    }
}

Error

This function will return an error if the provided path doesn't exist, if the process lacks permissions to view the contents or if the path points at a non-directory file
