Fields

sort_mode: ContainersSortMode

inspect_cache: InspectCache

logs_cache: LogsCache

refresh_batch: Option<RefreshBatch>

Currently-running R batch, if any. None when idle.

auto_list_in_flight: HashSet<String>

Aliases whose docker ps listing was kicked off by the scroll-driven auto-refresh helper and has not yet returned. Lets the helper skip a re-spawn while one is already pending. Cleared by handle_container_listing on arrival.

view_mode: ViewMode

Toggle for the per-row detail panel on the right. Mirrors the host-list v toggle. Default Detailed so the panel is visible whenever the terminal is wide enough.

collapsed_hosts: HashSet<String>

Aliases whose container group is currently collapsed in the AlphaHost rendering. Persisted across sessions via preferences so a folded group stays folded after restart.

view_cache: RefCell<Option<(u64, Vec<ContainerListItem>)>>

Memoized render list. The render and handler paths call visible_items repeatedly (24 call sites, several per key event) and each call cloned 6 String fields per container. The cache stores the built Vec<ContainerListItem> keyed on a content fingerprint over the inputs (sort_mode, search query, collapsed_hosts, per-host (timestamp, container_count)). On a hit we skip the collect/sort/intersperse step entirely and return a clone of the cached vec. The fingerprint walks all hosts but only reads a few fields each, so it is dramatically cheaper than rebuilding the row set.

Implementations

impl ContainersOverviewState

pub fn start_refresh(&mut self, batch: RefreshBatch)

Install a fresh refresh batch. Caller is responsible for spawning the initial parallel listings after this call; this method only owns the state slot.

pub fn clear_refresh(&mut self)

Drop the active refresh batch. Called when the queue drains and in-flight count returns to zero.

pub fn set_view_mode(&mut self, mode: ViewMode) -> Result<()>

Update view_mode and persist. Returns the persist error so the caller can surface it (current call site discards it intentionally to match the pre-encapsulation behavior where view-mode persist failures only logged).

pub fn set_sort_mode(&mut self, mode: ContainersSortMode) -> Result<()>

Update sort_mode and persist. Same contract as set_view_mode; the call site does surface the error via a toast.

pub fn migrate_alias(&mut self, old: &str, new: &str) -> bool

Rename an alias across every alias-keyed set in this state. Returns true when collapsed_hosts changed so the caller can persist; auto_list_in_flight and refresh_batch.in_flight_aliases are also migrated but are not persistent so they do not affect the return value. No-op (returns false) when old == new.

Trait Implementations

impl Debug for ContainersOverviewState

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for ContainersOverviewState

fn default() -> Self

Returns the “default value” for a type.
