Struct AppState 

pub struct AppState {
    pub xil_exe: PathBuf,
    pub status: StatusFn,
    pub(crate) jobs: Mutex<HashMap<u64, UnboundedReceiver<JobEvent>>>,
    pub(crate) next_job: AtomicU64,
    pub(crate) episodes_cache: Mutex<HashMap<PathBuf, (Instant, Rows)>>,
    pub grade_cache: Mutex<BTreeMap<String, String>>,
    pub(crate) choices: Mutex<Option<Arc<Choices>>>,
}

Everything a handler needs. Workspace paths are read from the environment on each call, as the Python module does.

Fields

xil_exe: PathBuf

The xil executable stages run under.

status: StatusFn

jobs: Mutex<HashMap<u64, UnboundedReceiver<JobEvent>>>

next_job: AtomicU64

episodes_cache: Mutex<HashMap<PathBuf, (Instant, Rows)>>

_EPISODES_CACHE: rows memoised per workspace root.

grade_cache: Mutex<BTreeMap<String, String>>

_sfx_grade_cache: {path: grade}, rebuilt only on Load/Refresh.

choices: Mutex<Option<Arc<Choices>>>

Implementations

impl AppState

pub fn new(xil_exe: PathBuf, status: StatusFn) -> Arc<AppState>

pub fn choices(&self) -> Arc<Choices>

The cached dropdown lists, built on first use. Blocking.

pub fn invalidate_choices(&self)

Drop the cached lists so the next request rebuilds them.

pub(crate) fn job_id(&self) -> u64
