Crate typed_arrow_dyn

Expand description

Dynamic runtime facade for typed-arrow.

This crate provides minimal runtime schema and builders abstractions that complement the compile-time APIs in typed-arrow.

Structs§

DynBuilders: Dynamic builders collection for a runtime schema.
DynCellRef: Borrowed representation of a single value backed by a raw pointer payload.
DynFixedSizeListView: View over a fixed-size list.
DynListView: View over List<T> / LargeList<T> values.
DynMapView: View over a map column.
DynProjection: Column projection descriptor used to derive projected dynamic views.
DynRow: A thin row wrapper used to append into a set of dynamic column builders.
DynRowOwned: Owned dynamic row that retains schema metadata alongside owned cell payloads.
DynRowRaw: Lifetime-erased dynamic row produced by DynRowView::into_raw.
DynRowView: Borrowed dynamic row backed by an arrow_array::RecordBatch.
DynRowViews: Iterator over borrowed dynamic rows.
DynSchema: A runtime Arrow schema wrapper used by the unified facade.
DynStructView: View over a struct column.
DynUnionView: View over a union value.

DynCell: A dynamic cell to be appended into a dynamic column builder.
DynCellRaw: Lifetime-erased counterpart to DynCellRef.
DynError: Errors that can occur when appending dynamic rows/cells.
DynViewError: Errors that can occur when constructing dynamic views over Arrow data.

DynColumnBuilder: Trait object for a column builder that accepts dynamic cells.

iter_batch_views: Create dynamic views for a batch using the provided schema reference.
new_dyn_builder: Factory function that returns a dynamic builder for a given DataType.
validate_nullability: Validate that arrays satisfy nullability constraints declared by schema. Returns the first violation encountered with a descriptive path.
view_batch_row: Borrow a single row from batch as a dynamic view after schema validation.
