Trait re_sdk::LoggableBatch

pub trait LoggableBatch {
    type Name;

    // Required methods
    fn name(&self) -> Self::Name;
    fn num_instances(&self) -> usize;
    fn arrow_field(&self) -> Field;
    fn to_arrow(&self) -> Result<Box<dyn Array>, SerializationError>;
}

A LoggableBatch represents an array’s worth of Loggable instances, ready to be serialized.

LoggableBatch is carefully designed to be erasable (“object-safe”), so that it is possible to build heterogeneous collections of LoggableBatchs (e.g. Vec<dyn LoggableBatch>). This erasability is what makes extending Archetypes possible with little effort.

You should almost never need to implement LoggableBatch manually, as it is already blanket implemented for most common use cases (arrays/vectors/slices of loggables, etc).

Required Associated Types

type Name

Required Methods

fn name(&self) -> Self::Name

The fully-qualified name of this batch, e.g. rerun.datatypes.Vec2D.

fn num_instances(&self) -> usize

The number of component instances stored into this batch.

fn arrow_field(&self) -> Field

The underlying arrow2::datatypes::Field, including datatype extensions.

fn to_arrow(&self) -> Result<Box<dyn Array>, SerializationError>

Serializes the batch into an Arrow array.
