Enum re_types_core::MaybeOwnedComponentBatch

pub enum MaybeOwnedComponentBatch<'a> {
    Owned(Box<dyn ComponentBatch>),
    Ref(&'a dyn ComponentBatch),
}

Holds either an owned ComponentBatch that lives on heap, or a reference to one.

This doesn’t use std::borrow::Cow on purpose: Cow requires Clone, which would break object-safety, which would prevent us from erasing ComponentBatchs in the first place.

Variants

Owned(Box<dyn ComponentBatch>)

Ref(&'a dyn ComponentBatch)

Trait Implementations

impl<'a> AsRef<dyn ComponentBatch<Name = ComponentName> + 'a> for MaybeOwnedComponentBatch<'a>

fn as_ref(&self) -> &(dyn ComponentBatch + 'a)

Converts this type into a shared reference of the (usually inferred) input type.

impl<'a> Deref for MaybeOwnedComponentBatch<'a>

type Target = dyn ComponentBatch<Name = ComponentName> + 'a

The resulting type after dereferencing.

fn deref(&self) -> &(dyn ComponentBatch + 'a)

Dereferences the value.

impl<'a> From<&'a dyn ComponentBatch<Name = ComponentName>> for MaybeOwnedComponentBatch<'a>

fn from(comp_batch: &'a dyn ComponentBatch) -> Self

Converts to this type from the input type.

impl From<Box<dyn ComponentBatch<Name = ComponentName>>> for MaybeOwnedComponentBatch<'_>

fn from(comp_batch: Box<dyn ComponentBatch>) -> Self

Converts to this type from the input type.

impl<'a> LoggableBatch for MaybeOwnedComponentBatch<'a>

type Name = ComponentName

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) -> SerializationResult<Box<dyn Array>>

Serializes the batch into an Arrow array.
