Struct HostState 

pub struct HostState { /* private fields */ }

Host, group, sort and view state grouped off the App god-struct. Holds the parsed ~/.ssh/config, the resolved host + pattern entries, the display list built from them, the render cache, the undo stack for deletions, the multi-select set for bulk snippet runs and all sort / group / view UI-state. Pure state container.

Implementations

impl HostState

pub fn from_config( ssh_config: SshConfigFile, hosts: Vec<HostEntry>, patterns: Vec<PatternEntry>, display_list: Vec<HostListItem>, ) -> Self

Construct from a loaded config and pre-resolved host/pattern lists.

pub fn set_group_by(&mut self, by: GroupBy)

Change the group-by mode and reset any active group filter in lockstep. Callers that change group_by directly would leave a stale group_filter referring to a group that no longer exists.

pub fn toggle_view_mode(&mut self)

Flip the host list between Compact and Detailed view.

pub fn toggle_multi_select(&mut self, idx: usize) -> bool

Toggle multi-select membership for the host at idx. Returns true when idx is now selected (was inserted) and false when it is now unselected (was removed) so the caller can react without re-reading the set.

pub fn ssh_config(&self) -> &SshConfigFile

pub fn ssh_config_mut(&mut self) -> &mut SshConfigFile

pub fn set_ssh_config(&mut self, config: SshConfigFile)

pub fn list(&self) -> &Vec<HostEntry>

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

pub fn patterns(&self) -> &Vec<PatternEntry>

pub fn patterns_mut(&mut self) -> &mut Vec<PatternEntry>

pub fn display_list(&self) -> &Vec<HostListItem>

pub fn display_list_mut(&mut self) -> &mut Vec<HostListItem>

pub fn render_cache(&self) -> &HostListRenderCache

pub fn render_cache_mut(&mut self) -> &mut HostListRenderCache

pub fn invalidate_render_cache(&mut self)

Invalidate the host-list render cache after a mutation.

pub fn undo_stack(&self) -> &Vec<DeletedHost>

pub fn undo_stack_mut(&mut self) -> &mut Vec<DeletedHost>

pub fn pop_undo(&mut self) -> Option<DeletedHost>

Drop the most recent deletion off the undo stack, if any.

pub fn clear_undo(&mut self)

Clear the undo stack. Positions may have shifted after a reload.

pub fn multi_select(&self) -> &HashSet<usize>

pub fn multi_select_mut(&mut self) -> &mut HashSet<usize>

pub fn clear_multi_select(&mut self)

Clear the multi-select set. Idempotent.

pub fn sort_mode(&self) -> SortMode

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

pub fn advance_sort_mode(&mut self)

Advance the sort mode to the next variant in the cycle.

pub fn group_by(&self) -> &GroupBy

pub fn set_group_by_raw(&mut self, by: GroupBy)

Set the group-by mode without touching the active group filter. Use when restoring saved state. set_group_by resets the filter.

pub fn view_mode(&self) -> ViewMode

pub fn set_view_mode(&mut self, mode: ViewMode)

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

pub fn set_group_filter(&mut self, filter: Option<String>)

pub fn group_tab_order(&self) -> &Vec<String>

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