Expand description

File system implementations must implement this trait All path parameters are absolute, starting with ‘/’, except for the root directory which is simply the empty string (i.e. “”) The character ‘/’ is used to delimit directories on all platforms. Path components may be any UTF-8 string, except “/”, “.” and “..”

Please use the test_macros [test_macros::test_vfs!] and [test_macros::test_vfs_readonly!]

Required Methods§

Source

fn read_dir( &self, path: &str, ) -> VfsResult<Box<dyn Iterator<Item = String> + Send>>

Iterates over all direct children of this directory path NOTE: the returned String items denote the local bare filenames, i.e. they should not contain “/” anywhere
