Methods

impl<U> Vfs<U>

fn new() -> Vfs<U>

Creates a new, empty VFS.

fn file_saved(&self, path: &Path) -> Result<(), Error>

Indicate that the current file as known to the VFS has been written to disk.

fn flush_file(&self, path: &Path) -> Result<(), Error>

Removes a file from the VFS. Does not check if the file is synced with the disk. Does not check if the file exists.

fn file_is_synced(&self, path: &Path) -> Result<bool, Error>

fn on_changes(&self, changes: &[Change]) -> Result<(), Error>

Record a set of changes to the VFS.

fn get_cached_files(&self) -> HashMap<PathBuf, String>

Return all files in the VFS.

fn get_changes(&self) -> HashMap<PathBuf, String>

fn has_changes(&self) -> bool

Returns true if the VFS contains any changed files.
