Struct re_space_view_spatial::visualizers::utilities::labels::LabeledBatch

pub struct LabeledBatch<'a, P: 'a, I: Iterator<Item = P> + 'a> {
    pub entity_path: &'a EntityPath,
    pub num_instances: usize,
    pub overall_position: P,
    pub instance_positions: I,

}

Inputs for process_labels(), defining the label(s) of a single batch.

• P is the type of the positions of the labels, which might be 3D or 2D.
• I is the type of the iterator over positions.

Fields

entity_path: &'a EntityPath

num_instances: usize

num_instances should be equal to the length of instance_positions.

overall_position: P

The position where a single shared label will be displayed if it is. This is typically the center of the bounding box of the entity.

instance_positions: I

Note: If we find a reason to make this data type usable more than once, replace this Iterator with IntoIterator.

labels: &'a [ArrowString]

Label data from the batch.

Length 1 is treated as a label for the whole batch.

The number of per-instance labels actually drawn is the minimum of the lengths of instance_positions and labels.

colors: &'a [Color32]

Colors from the batch to apply to the labels.

Length 1 is treated as a color for the whole batch.

show_labels: ShowLabels

The ShowLabels component value.

If no value is available from the data, use show_labels_fallback to obtain it.

annotation_infos: &'a ResolvedAnnotationInfos
