Events posted to the UI thread from background threads or timers.

Non-exhaustive: a match on it outside teksilo-core needs a wildcard arm.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

BackgroundComplete

A background operation completed.

Fields

operation_id: String

BackgroundProgress

A background operation reports progress.

Fields

operation_id: String

percent: f32

message: String

External(Box<dyn Any + Send>)

An external event from any source (type-erased for extensibility).

SubscriptionEvent

A backend event delivered to a widget that subscribed via BuildContext::subscribe_event. The sub_id keys the UI-side callback in the tree’s TreeAppContext::subscription_callbacks map; the event is downcast back to the subscriber’s expected type.

Fields

sub_id: SubscriptionId

event: Box<dyn Any + Send>

I18nReload

An .ftl translation file registered via I18nConfig::runtime_override(locale, path) changed on disk. The teksilo-app handler calls I18nManager::reload_from_path and bumps the translation version signal.

Fields

locale: String

path: PathBuf

SettingsReload

A settings file managed by teksilo-settings changed on disk — either a peer process’s write, or (harmlessly) this very process’s own write being noticed by its own watcher. The teksilo-app handler looks path up in the app’s teksilo_settings::SettingsRegistry (via app_state) and calls Reloadable::reload_from_disk on whatever owns it — a no-op if nothing is registered for that path, or if the content is unchanged (the self-write case).

Fields

path: PathBuf

SettingsWriteFailed

A teksilo-settings DebouncedWriter gave up on a queued write — after MAX_WRITE_ATTEMPTS retries, or at Unregister teardown with a write still failing. The queued patches for path were permanently discarded.

Fields

path: PathBuf

attempts: u32

dropped_patches: usize

message: String
