}

A single column of component data.

Abstracts over the different possible arrow representation of component data.

values: ListArray<i32>

Implementations

impl ComponentData

fn try_new( descriptor: &ComponentColumnDescriptor, column_data: &Box<dyn ArrowArray> ) -> Result<Self, DisplayRecordBatchError>

fn instance_count(&self, row_index: usize) -> u64

Returns the number of instances for the given row index.

For Self::Null columns, or for invalid row_index, this will return 0.

fn data_ui( &self, ctx: &ViewerContext<'_>, ui: &mut Ui, latest_at_query: &LatestAtQuery, entity_path: &EntityPath, component_name: ComponentName, row_index: usize, instance_index: Option<u64> )

Display some data from the column.

• Argument row_index is the row index within the batch column.
• Argument instance_index is the specific instance within the specified row. If None, a summary of all existing instances is displayed.

Panic

Panics if instance_index is out-of-bound. Use Self::instance_count to ensure correctness.

Trait Implementations

impl Debug for ComponentData

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
