Struct FilesystemDataStore 

pub struct FilesystemDataStore { /* private fields */ }

DataStore implementation backed by the real filesystem.

State is stored as symlinks and sentinel files under the XDG data directory. The double-link architecture works as follows:

~/dotfiles/vim/vimrc                              (source)
  -> ~/.local/share/dodot/packs/vim/symlink/vimrc (data link)
    -> ~/.vimrc                                   (user link)

Implementations

impl FilesystemDataStore

pub fn new( fs: Arc<dyn Fs>, paths: Arc<dyn Pather>, runner: Arc<dyn CommandRunner>, ) -> Self

Trait Implementations

impl DataStore for FilesystemDataStore

fn create_data_link( &self, pack: &str, handler: &str, source_file: &Path, ) -> Result<PathBuf>

Creates an intermediate symlink in the datastore: handler_data_dir(pack, handler) / filename -> source_file

fn create_user_link( &self, datastore_path: &Path, user_path: &Path, ) -> Result<()>

Creates a user-visible symlink: user_path -> datastore_path

fn run_and_record( &self, pack: &str, handler: &str, executable: &str, arguments: &[String], sentinel: &str, force: bool, ) -> Result<()>

Executes command via shell and records a sentinel on success.

fn has_sentinel( &self, pack: &str, handler: &str, sentinel: &str, ) -> Result<bool>

Checks whether a sentinel exists for this pack/handler.

fn remove_state(&self, pack: &str, handler: &str) -> Result<()>

Removes all state for a pack/handler pair.

fn has_handler_state(&self, pack: &str, handler: &str) -> Result<bool>

Checks if any state exists for a pack/handler pair.

fn list_pack_handlers(&self, pack: &str) -> Result<Vec<String>>

Lists handler names that have state for a pack.

fn list_handler_sentinels( &self, pack: &str, handler: &str, ) -> Result<Vec<String>>

Lists sentinel file names for a pack/handler.

fn write_rendered_file( &self, pack: &str, handler: &str, filename: &str, content: &[u8], ) -> Result<PathBuf>

Writes a regular file (not a symlink) into the datastore.

fn write_rendered_dir( &self, pack: &str, handler: &str, relative: &str, ) -> Result<PathBuf>

Creates a directory (mkdir -p) inside the datastore and returns its absolute path. Used for preprocessor-expanded directory entries (e.g. directory markers from tar archives).

fn sentinel_path(&self, pack: &str, handler: &str, sentinel: &str) -> PathBuf

Returns the absolute path where a sentinel file would be stored.
