Expand description

The complete application state for the TUI browser.

This struct holds all state needed to render and interact with the TUI, including:

  • The Vortex session and file being browsed
  • Navigation state (current cursor position, selected tab)
  • Input mode and search filter state
  • UI state for lists and grids

The state is preserved when switching between tabs, allowing users to return to their previous position.

Fields§

§session: VortexSession

The Vortex session used to read array data during rendering.

§key_mode: KeyMode

The current input mode (normal navigation or search).

§search_filter: String

The current search filter string (only used in search mode).

§filter: Option<Vec<bool>>

A boolean mask indicating which children match the current search filter.

None when no filter is active, Some(vec) when filtering where vec[i] indicates whether child i should be shown.

§vxf: VortexFile

The open Vortex file being browsed.

§cursor: LayoutCursor

The current position in the layout hierarchy.

§current_tab: Tab

The currently selected tab.

§layouts_list_state: ListState

Selection state for the layout children list.

§segment_grid_state: SegmentGridState

State for the segment grid display.

§frame_size: Size

The size of the last rendered frame.

§tree_scroll_offset: u16

Vertical scroll offset for the encoding tree display in flat layout view.

§cached_flat_array: Option<ArrayRef>

Cached array data for the current FlatLayout, loaded asynchronously on WASM.

§cached_flatbuffer_size: Option<usize>

Cached flatbuffer size for the current FlatLayout, loaded asynchronously on WASM.

§query_state: QueryState

State for the Query tab.

§file_path: String

File path for use in query execution.

Implementations§

Source§

impl AppState

Source

pub async fn new( session: &VortexSession, path: impl AsRef<Path>, ) -> VortexResult<AppState>

Create a new application state by opening a Vortex file from a path.

§Errors

Returns an error if the file cannot be opened or read.

Clear the current search filter and return to showing all children.

Source

pub fn reset_layout_view_state(&mut self)

Reset the layout view state after navigating to a different layout.

This resets the list selection to the first item and clears any scroll offset. The caller is responsible for awaiting load_flat_data() afterward if the new layout is a Flat.
