Required Methods

fn lookup_directory(&self, context: &mut Context, path: &Path) -> Result<()>

fn lookup_file( &self, context: &mut Context, path: &Path, flags: Flags, ) -> Result<()>

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

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

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

Remove a file or directory from the file system.

Permanently deletes the specified file or directory. For directories, they must be empty before they can be removed.

Arguments

• context - File system context
• path - Path to the file or directory to remove

Returns

• Ok(()) - File or directory successfully removed
• Err(Error) - Error during removal

Errors

• crate::Error::NotFound - File or directory doesn’t exist
• crate::Error::PermissionDenied - Insufficient permissions
• crate::Error::DirectoryNotEmpty - Directory contains files
• crate::Error::RessourceBusy - File is currently in use

fn rename(&self, source: &Path, destination: &Path) -> Result<()>

Rename or move a file or directory.

Changes the name or location of a file or directory. This can be used for both renaming within the same directory and moving between directories.

Arguments

• context - File system context
• source - Current path of the file or directory
• destination - New path for the file or directory

Returns

• Ok(()) - File or directory successfully renamed/moved
• Err(Error) - Error during rename operation

Errors

• crate::Error::NotFound - Source file doesn’t exist
• crate::Error::AlreadyExists - Destination already exists
• crate::Error::PermissionDenied - Insufficient permissions

fn get_attributes(&self, path: &Path, attributes: &mut Attributes) -> Result<()>

fn set_attributes(&self, path: &Path, attributes: &Attributes) -> Result<()>
