Macro testdir::init_testdir

macro_rules! init_testdir {
    () => { ... };
}

Initialises the global NumberedDir used by the testdir macro.

This macro is implicitly called by the testdir macro to initialise the global NumberedDir instance with a base of the Cargo package name calling the macro. It must be called before any call to with_testdir to ensure this is initialised.

Examples

use testdir::{init_testdir, with_testdir};

init_testdir!();
let path = with_testdir(|dir| dir.create_subdir("some/subdir").unwrap());
assert!(path.is_dir());
assert!(path.ends_with("some/subdir"));
