create_dir

fn create_dir(string path) -> Result<unit, IoError>

use io::fs::{create_dir};

Creates the directory path.

The parent must already exist (else Err(IoError::NotFound)), and path must not (else Err(IoError::AlreadyExists)). Use create_dir_all to create missing parents too. Needs --allow-write.

Parameters#

Returns#

Result<unit, IoError>

Examples#

use io::{IoError};
use io::fs::{create_dir, is_dir, remove_dir};
use tests::assert;
let dir = "/tmp/coil_doc_fs_create_dir";
let made = match create_dir(dir) {
    Result::Ok(_) => true,
    Result::Err(_) => false,
};
let again = match create_dir(dir) {
    Result::Err(IoError::AlreadyExists) => true,
    default => false,
};
let dir_now = match is_dir(dir) {
    Result::Ok(b) => b,
    Result::Err(_) => false,
};
let _ = remove_dir(dir);
assert!(made && again && dir_now);
