Struct TunnelState 

pub struct TunnelState { /* private fields */ }

Tunnel-owned state grouped off the App god-struct. Contains the rule list, the edit form, the live child-process map, form baseline for the dirty check, the pending delete index and the cached per-host summary strings. Pure state container; behaviour lives on App or on dedicated methods here.

Implementations

impl TunnelState

pub fn list(&self) -> &[TunnelRule]

pub fn list_mut(&mut self) -> &mut Vec<TunnelRule>

pub fn form(&self) -> &TunnelForm

pub fn form_mut(&mut self) -> &mut TunnelForm

pub fn reset_form(&mut self)

pub fn active(&self) -> &HashMap<String, ActiveTunnel>

pub fn active_get(&self, alias: &str) -> Option<&ActiveTunnel>

pub fn active_get_mut(&mut self, alias: &str) -> Option<&mut ActiveTunnel>

pub fn active_contains(&self, alias: &str) -> bool

pub fn active_insert(&mut self, alias: String, tunnel: ActiveTunnel)

pub fn active_remove(&mut self, alias: &str) -> Option<ActiveTunnel>

pub fn drain_active(&mut self) -> Drain<'_, String, ActiveTunnel>

pub fn clear_active(&mut self)

pub fn pending_delete(&self) -> Option<usize>

pub fn take_pending_delete(&mut self) -> Option<usize>

pub fn sort_mode(&self) -> TunnelSortMode

pub fn set_sort_mode(&mut self, mode: TunnelSortMode)

pub fn form_baseline(&self) -> Option<&TunnelFormBaseline>

pub fn set_form_baseline(&mut self, baseline: Option<TunnelFormBaseline>)

pub fn demo_live_snapshots(&self) -> &HashMap<String, TunnelLiveSnapshot>

pub fn demo_live_snapshots_mut( &mut self, ) -> &mut HashMap<String, TunnelLiveSnapshot>

pub fn parser_tx(&self) -> Sender<ParserMessage>

pub fn clients(&self) -> &HashMap<u16, Vec<ClientPeer>>

pub fn peer_viz(&self) -> &HashMap<(u16, String), [u64; 12]>

pub fn peer_viz_last_push(&self) -> Option<Instant>

pub fn peer_viz_prev_push(&self) -> Option<Instant>

pub fn summaries_cache(&self) -> &HashMap<String, String>

pub fn summaries_cache_mut(&mut self) -> &mut HashMap<String, String>

pub fn request_delete(&mut self, idx: usize)

Open a delete confirmation for the tunnel at idx. The renderer reads pending_delete to draw the confirm overlay.

pub fn cancel_delete(&mut self)

Dismiss a pending delete confirmation. Idempotent.

pub fn ensure_lsof_poller(&mut self)

Ensure the shared lsof poller is running. Idempotent: a second call after the poller is already up is a noop. Caller is responsible for updating bind_ports afterwards.

pub fn set_lsof_ports(&self, ports: Vec<(String, u16, u32)>)

Replace the lsof poller’s port list. Callers compute the (alias, bind_port, tunnel_pid) tuples from the SSH config directives because ActiveTunnel does not store the rule set directly. The poller picks up the new list on its next iteration.

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

Drain the parser channel into per-tunnel live state, drain the lsof channel into the shared clients and conflicts maps, rotate per-tunnel history buckets and finally poll every active child for exit. Returns (alias, message, is_error) tuples so the outer loop can route them through notify_*.

pub fn push_peer_viz(&mut self, now: Instant)

Push one bucket of per-peer braille history. Called exactly once per lsof arrival so the visible window encodes PEER_VIZ_BUCKETS consecutive poll snapshots — long enough to see the trend, short enough to react quickly to changes. The renderer fills in smooth motion between pushes via peer_viz_last_push / peer_viz_prev_push. Garbage-collects entries for peers that no longer appear in self.clients.

pub fn prune_orphans(&mut self, valid_aliases: &HashSet<&str>)

Drop demo-mode tunnel snapshots whose alias is no longer in valid_aliases. Called from App::reload_hosts. Outside demo the map stays empty so this is a no-op, but a demo workflow that renames or deletes a host should not leak the old snapshot.

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

Move the active-tunnel handle from old to new on host rename. Called from App::migrate_alias_keyed_caches before reload_hosts, whose prune step would otherwise drop entries still under the old alias. No-op when old == new or no active tunnel exists under old.

Trait Implementations

impl Default for TunnelState

fn default() -> Self

Returns the “default value” for a type.

impl Drop for TunnelState

fn drop(&mut self)

Executes the destructor for this type.

fn pin_drop(self: Pin<&mut Self>)

🔬This is a nightly-only experimental API. (pin_ergonomics)

Execute the destructor for this type, but different to Drop::drop, it requires self to be pinned.
