Struct SessionDirs 

pub struct SessionDirs {
    pub state_store: Arc<JsonFileStore>,
    pub card_store: Arc<FileCardStore>,
    pub scenarios_dir: PathBuf,
    pub nn_dir: PathBuf,
}

Per-session storage roots resolved by the service layer.

Bundles the four filesystem handles that flow into every Executor::start_session / Executor::start_session_with_env call so callers don’t juggle four parallel arguments. The service layer builds one from algocline_core::AppDir and hands it in; the engine consumes fields as needed.

Adding a new subsystem-owned path (e.g. a future blob_dir) is a single field on this struct rather than a sweep across every start_session caller.

Fields

state_store: Arc<JsonFileStore>

Backing store for alc.state.* (typically <app_dir>/state).

card_store: Arc<FileCardStore>

Backing store for alc.card.* (typically <app_dir>/cards).

scenarios_dir: PathBuf

Directory exposed to Lua via alc._dirs.scenarios.

nn_dir: PathBuf

Store root for alc.nn.save / alc.nn.load (typically <app_dir>/nn). An empty PathBuf disables the store install (save/load then error); consumed only when the nn feature is enabled.

Trait Implementations

impl Clone for SessionDirs

fn clone(&self) -> SessionDirs

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.
