Implementations

impl App

pub fn new(refresh_secs: u64, theme: ThemeMode) -> Self

pub fn persist_theme(&mut self)

Remembers the current theme across sessions.

pub fn restore_warehouse_pref(&mut self)

Restores the remembered warehouse for the active profile.

pub fn splash_active(&self) -> bool

pub fn dismiss_splash(&mut self)

pub fn any_fresh(&self) -> bool

True while any pane’s data just landed — keeps the flash decaying.

pub fn open_picker(&mut self)

pub fn picker_next(&mut self)

pub fn picker_prev(&mut self)

pub fn picker_select(&mut self) -> Option<Arc<DatabricksCli>>

Confirms the picker selection; returns the new CLI handle to use.

pub fn open_problems(&mut self)

Collects everything unhealthy across the loaded panes: items whose status is failed, or whose most recent run failed.

pub fn problems_next(&mut self)

pub fn problems_prev(&mut self)

pub fn problems_jump(&mut self)

Jumps focus and selection to the highlighted problem’s pane item.

pub fn fetch_host(&mut self, cli: &Arc<DatabricksCli>)

Resolves the workspace host in the background — auth describe can take seconds when it refreshes tokens, so it must not block the loop.

pub fn poll_host(&mut self)

pub fn selection(&self, idx: usize) -> usize

Selection index for a panel, clamped to the current list length.

pub fn select_next(&mut self)

pub fn select_prev(&mut self)

pub fn filter_start(&mut self)

Opens filter entry for the focused pane, starting from scratch.

pub fn filter_push(&mut self, c: char)

pub fn filter_pop(&mut self)

pub fn filter_accept(&mut self)

Keeps the filter applied and returns keys to normal navigation.

pub fn filter_clear(&mut self)

pub fn active_filter(&self) -> &str

The focused pane’s filter, if any.

pub fn open_detail(&mut self, cli: &Arc<DatabricksCli>)

pub fn uc_drill(&mut self, cli: &Arc<DatabricksCli>) -> bool

Descends one level in the Unity Catalog tree. Returns false when the selection is a leaf (caller should open the detail view instead).

pub fn uc_up(&mut self, cli: &Arc<DatabricksCli>) -> bool

Ascends one level; returns false if already at the catalog root.

pub fn resource_name(&self, kind: &str, id: &str) -> Option<String>

Looks up a resource’s display name by id in the loaded panes — lets the cost view show “nightly-etl” instead of a job id.

pub fn warehouses(&self) -> Vec<(String, String, bool)>

All known warehouses as (name, id, running).

pub fn open_preview(&mut self, cli: &Arc<DatabricksCli>, force_pick: bool)

Runs a sample-data query for the selected table or view. With force_pick (or several warehouses and no remembered choice) a warehouse picker opens first.

pub fn open_cost(&mut self, cli: &Arc<DatabricksCli>)

Opens the DBU usage view, resolving a warehouse like previews do.

pub fn open_lineage(&mut self, cli: &Arc<DatabricksCli>)

Opens the lineage view for the selected table/view; needs a warehouse since lineage lives in system tables.

pub fn close_cost(&mut self)

pub fn open_sql(&mut self)

Opens the SQL console. With a table/view selected in the catalog pane, the prompt starts as an editable query against it.

pub fn close_sql(&mut self)

pub fn sql_input(&self) -> Option<String>

The statement currently in the prompt.

pub fn sql_set_input(&mut self, s: &str)

Replaces the prompt contents (after an $EDITOR round-trip).

pub fn hist_search_current(&self) -> Option<&String>

The history entry the active Ctrl+R search currently matches.

pub fn hist_search_start(&mut self)

pub fn hist_search_push(&mut self, c: char)

pub fn hist_search_pop(&mut self)

pub fn hist_search_older(&mut self)

Ctrl+R again: step to the next older match.

pub fn hist_search_accept(&mut self)

pub fn hist_search_cancel(&mut self)

pub fn sql_push(&mut self, c: char)

pub fn sql_pop(&mut self)

Backspace: deletes the character before the caret.

pub fn sql_delete(&mut self)

Delete: removes the character under the caret.

pub fn sql_left(&mut self)

pub fn sql_right(&mut self)

pub fn sql_hist_prev(&mut self)

↑ at the prompt: step back through history, stashing the draft.

pub fn sql_hist_next(&mut self)

↓ at the prompt: step forward, back to the stashed draft at the end.

pub fn sql_home(&mut self)

pub fn sql_end(&mut self)

pub fn sql_scroll(&mut self, delta: i32)

pub fn sql_run(&mut self, cli: &Arc<DatabricksCli>)

Runs the typed statement, resolving a warehouse like previews do.

Ctrl+S in the console: export the current results.

pub fn preview_export(&mut self)

e in a table preview: export the sampled rows.

pub fn poll_sql(&mut self) -> bool

pub fn poll_cost(&mut self) -> bool

pub fn wh_picker_next(&mut self)

pub fn wh_picker_prev(&mut self)

pub fn wh_picker_cancel(&mut self)

pub fn wh_picker_select(&mut self, cli: &Arc<DatabricksCli>)

Confirms the warehouse choice, remembers it, and starts the preview.

pub fn close_preview(&mut self)

pub fn poll_preview(&mut self) -> bool

pub fn preview_scroll(&mut self, delta: i32)

pub fn poll_uc(&mut self) -> bool

pub fn open_grants(&mut self, cli: &Arc<DatabricksCli>)

Opens the access view for the selected item: effective UC grants or the workspace object ACL.

pub fn open_run(&mut self, cli: &Arc<DatabricksCli>)

Drills from an open job or pipeline detail into its most recent run/update.

pub fn close_run(&mut self)

pub fn run_nav(&mut self, cli: &Arc<DatabricksCli>, delta: i32)

Moves to an older (delta > 0) or newer (delta < 0) run.

pub fn run_toggle_raw(&mut self)

pub fn run_scroll(&mut self, delta: i32)

pub fn poll_run(&mut self, cli: &Arc<DatabricksCli>) -> bool

Applies run fetch results; also re-polls a live run every few seconds so an executing run’s tasks update on their own.

pub fn close_detail(&mut self)

pub fn toggle_raw(&mut self)

pub fn poll_detail(&mut self) -> bool

Applies a finished detail fetch; returns true if the UI should redraw.

pub fn detail_scroll(&mut self, delta: i32)

pub fn request_action(&mut self)

Prepares a contextual action for the selected item, pending confirmation: start/stop for clusters, warehouses and pipelines, run-now for jobs.

pub fn cancel_confirm(&mut self)

pub fn confirm_execute(&mut self, cli: &Arc<DatabricksCli>)

pub fn poll_action(&mut self, cli: &Arc<DatabricksCli>) -> bool

Applies a finished action; refreshes on success. Returns true on change.

pub fn expire_flash(&mut self) -> bool

Drops the flash message once it has been visible long enough.

pub fn open_in_browser(&self)

Opens the selected item (or the open detail view) in the workspace web UI.

pub fn status_counts(&self) -> (usize, usize, usize, usize)

Counts of (ok, pending, failed, idle) items across all panels.

pub fn last_refresh_age(&self) -> Duration

pub fn spinner(&self) -> &'static str

pub fn spinner_frame(&self) -> usize

pub fn busy(&self) -> bool

True whenever any background work is in flight — the loop uses this to keep spinners ticking, not just during panel refreshes.

pub fn tick_spinner(&mut self)

pub fn toggle_zoom(&mut self)

pub fn focus_next(&mut self)

pub fn focus_prev(&mut self)

pub fn needs_refresh(&self) -> bool

pub fn start_refresh(&mut self, cli: &Arc<DatabricksCli>)

pub fn poll_refresh(&mut self) -> bool

Applies any fetch results that have arrived; returns true if the UI should redraw.
