Crate teksilo_data 

Data model abstractions for Teksilo.

Provides reactive collection types (ListModel<T>, TreeModel<T>) and change notification enums (DataChange, TreeChange) for data-driven widgets like ListView, TreeView, and Repeater.

The two source traits — ListDataSource (flat) and TreeDataSource (hierarchical) — are the read-and-command interfaces every data view talks to. ListModel / TreeModel are built-in implementations; an external source of truth (e.g. a Qleany entity store) implements a source trait directly and so never mirrors itself into a built-in model. Each trait carries a capability protocol — identity (key_at/index_of), DnD validation (drag/can_accept/accept_drop/on_drag_out), and lazy loading (row_state/request_window/can_fetch_more/fetch_more) — as defaulted methods (see dnd_types).

Chart data follows the same shape: ChartModel<T> is the reactive, multi-series primary model (mirroring ListModel/TreeModel), with ChartWindow<T> / ChartAggregate<T> streaming/rollup projections and ChartSelection for point-level selection.

Modules

chart_aggregate

ChartAggregate<T> — a bucket/rollup projection over a crate::ChartModel.

chart_change

ChartChange — change notifications and stable series identifiers for chart collections.

chart_model

ChartModel<T> — concrete reactive multi-series chart data model.

chart_selection

ChartSelection — point-level selection state for chart widgets.

chart_window

ChartWindow<T> — a “last N points per series” streaming projection over a crate::ChartModel.

check_state

CheckState — tri-state checkbox value shared by the data layer and widgets.

checked_model

CheckedModel — per-row checkbox state for flat collection widgets.

data_change

DataChange — change notifications for flat collections.

debug_registry

debug_registry — opt-in registry of named data models for the Teksilo inspector.

dnd_types

Shared capability types for the data-source drag-and-drop + lazy protocol.

keyed_selection_model

KeyedSelectionModel<K> — identity-based selection for collection widgets.

keyed_tree_checked_model

KeyedTreeCheckedModel<K> — per-node checkbox state for a tree keyed by a stable domain id, with optional descendant→ancestor tristate aggregation.

list_data_source

ListDataSource — read-and-command interface for a flat collection behind a ListView / TableView.

SeriesPattern — the non-colour channel that identifies a chart series.

sort_filter_list_model

Composable sort + filter projection over a flat list source.

sort_filter_tree_model

Composable sort + filter projection over a hierarchical tree.

tree_change

TreeChange — change notifications and stable node identifiers for tree collections.

tree_checked_model

TreeCheckedModel — per-node checkbox state for a tree, with optional descendant→ancestor tristate aggregation.

tree_data_slice

TreeDataSlice — the reusable TreeDataSource engine for an external, indent-ordered tree (a Qleany entity store, a database, a virtual filesystem) that is NOT mirrored into a TreeModel.

tree_data_source

TreeDataSource — read-and-command interface for hierarchical data behind a TreeView / TreeTableView.

tree_model

TreeModel — concrete reactive tree with shared, cloneable handles.
