    fn remove_file(&self, _path: &str) -> Result<(), FileError> { ... }
}

Filesystem interface used by the VFS mount table for pseudo filesystems.

Required Methods

fn name(&self) -> &'static str

Human-readable filesystem name such as procfs, sysfs, or devtmpfs.

fn open_file(&self, path: &str) -> Result<Arc<Mutex<dyn File>>, FileError>

Open a file path relative to this virtual filesystem’s mount root.

fn stat_path(&self, path: &str) -> Result<FileMetadata, FileError>

Return file metadata for a path relative to this mount.

fn readdir_path(&self, path: &str) -> Result<Vec<String>, FileError>

List a virtual directory.

Provided Methods

fn create_file(&self, _path: &str) -> Result<Arc<Mutex<dyn File>>, FileError>

Virtual filesystems are read-mostly by default.

fn create_dir(&self, _path: &str) -> Result<(), FileError>

Virtual filesystems are read-mostly by default.

fn remove_file(&self, _path: &str) -> Result<(), FileError>

Virtual filesystems are read-mostly by default.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
