Struct StateCoordinator 

pub struct StateCoordinator {
    pub state_container: AppStateContainer,
    pub shadow_state: Rc<RefCell<ShadowStateManager>>,
    pub viewport_manager: Rc<RefCell<Option<ViewportManager>>>,
    pub hybrid_parser: HybridParser,
}

StateCoordinator manages and synchronizes all state components in the TUI This centralizes state management and reduces coupling in the main TUI

Fields

state_container: AppStateContainer

Core application state

shadow_state: Rc<RefCell<ShadowStateManager>>

Shadow state for tracking mode transitions

viewport_manager: Rc<RefCell<Option<ViewportManager>>>

Viewport manager for display state

hybrid_parser: HybridParser

SQL parser with schema information

Implementations

impl StateCoordinator

pub fn sync_mode_with_refs( state_container: &mut AppStateContainer, shadow_state: &RefCell<ShadowStateManager>, mode: AppMode, trigger: &str, )

Static version of sync_mode that works with references

pub fn update_parser_with_refs( state_container: &AppStateContainer, parser: &mut HybridParser, )

Static version of update_parser_for_current_buffer

pub fn new( state_container: AppStateContainer, shadow_state: Rc<RefCell<ShadowStateManager>>, viewport_manager: Rc<RefCell<Option<ViewportManager>>>, hybrid_parser: HybridParser, ) -> Self

pub fn sync_mode(&mut self, mode: AppMode, trigger: &str)

Synchronize mode across all state containers This ensures AppStateContainer, Buffer, and ShadowState are all in sync

pub fn set_mode_via_shadow_state(&mut self, mode: AppMode, trigger: &str)

Alternative mode setter that goes through shadow state

pub fn sync_after_buffer_switch(&mut self)

Synchronize all state after buffer switch This should be called after any buffer switch operation

pub fn update_parser_for_current_buffer(&mut self)

Update parser schema from current buffer’s DataView

pub fn enter_search_mode(&mut self, mode: SearchMode) -> String

Enter a search mode with proper state synchronization

pub fn cancel_search(&mut self) -> (Option<String>, Option<usize>)

Cancel search and properly restore state This handles all the complex state synchronization when Escape is pressed during search

pub fn cancel_search_with_refs( state_container: &mut AppStateContainer, shadow_state: &RefCell<ShadowStateManager>, vim_search_adapter: Option<&RefCell<VimSearchAdapter>>, )

Static version for delegation pattern with vim search adapter

pub fn should_handle_next_match( state_container: &AppStateContainer, vim_search_adapter: Option<&RefCell<VimSearchAdapter>>, ) -> bool

Check if ‘n’ key should navigate to next search match Returns true only if there’s an active search (not cancelled with Escape)

pub fn should_handle_previous_match( state_container: &AppStateContainer, vim_search_adapter: Option<&RefCell<VimSearchAdapter>>, ) -> bool

Check if ‘N’ key should navigate to previous search match Returns true only if there’s an active search (not cancelled with Escape)

pub fn complete_search_with_refs( state_container: &mut AppStateContainer, shadow_state: &RefCell<ShadowStateManager>, vim_search_adapter: Option<&RefCell<VimSearchAdapter>>, mode: AppMode, trigger: &str, )

Complete a search operation (after Apply/Enter is pressed) This keeps the pattern for n/N navigation but marks search as complete

pub fn apply_text_filter_with_refs( state_container: &mut AppStateContainer, pattern: &str, ) -> usize

pub fn reset_table_state_with_refs( state_container: &mut AppStateContainer, viewport_manager: &RefCell<Option<ViewportManager>>, )

Reset all table-related state to initial values This is typically called when switching data sources or after queries

Add a new DataView and coordinate all necessary state updates This centralizes the complex logic of adding a new data source

pub fn set_sql_query_with_refs( state_container: &mut AppStateContainer, shadow_state: &RefCell<ShadowStateManager>, parser: &mut HybridParser, table_name: &str, raw_table_name: &str, config: &Config, ) -> String

Set SQL query and update all related state This centralizes the complex logic of setting up SQL query state

pub fn handle_execute_query_with_refs( state_container: &mut AppStateContainer, shadow_state: &RefCell<ShadowStateManager>, query: &str, ) -> Result<bool, Error>

Handle query execution and all related state changes Returns true if application should exit

pub fn switch_to_results_after_query(&mut self)

Switch to Results mode after successful query execution

pub fn switch_to_results_after_query_with_refs( state_container: &mut AppStateContainer, shadow_state: &RefCell<ShadowStateManager>, )

Static version for delegation

pub fn apply_filter_search_with_refs( state_container: &mut AppStateContainer, shadow_state: &RefCell<ShadowStateManager>, pattern: &str, )
