Struct re_types::archetypes::DisconnectedSpace

pub struct DisconnectedSpace {
    pub disconnected_space: DisconnectedSpace,
}

Archetype: Spatially disconnect this entity from its parent.

Specifies that the entity path at which this is logged is spatially disconnected from its parent, making it impossible to transform the entity path into its parent’s space and vice versa. It only applies to space views that work with spatial transformations, i.e. 2D & 3D space views. This is useful for specifying that a subgraph is independent of the rest of the scene.

Example

Disconnected space

fn main() -> Result<(), Box<dyn std::error::Error>> {
    let rec = rerun::RecordingStreamBuilder::new("rerun_example_disconnected_space").spawn()?;

    // These two points can be projected into the same space..
    rec.log(
        "world/room1/point",
        &rerun::Points3D::new([(0.0, 0.0, 0.0)]),
    )?;
    rec.log(
        "world/room2/point",
        &rerun::Points3D::new([(1.0, 1.0, 1.0)]),
    )?;

    // ..but this one lives in a completely separate space!
    rec.log("world/wormhole", &rerun::DisconnectedSpace::new(true))?;
    rec.log(
        "world/wormhole/point",
        &rerun::Points3D::new([(2.0, 2.0, 2.0)]),
    )?;

    Ok(())
}

Fields

disconnected_space: DisconnectedSpace

Whether the entity path at which this is logged is disconnected from its parent.

Trait Implementations

impl Archetype for DisconnectedSpace

type Indicator = GenericIndicatorComponent<DisconnectedSpace>

The associated indicator component, whose presence indicates that the high-level archetype-based APIs were used to log the data.

fn name() -> ArchetypeName

The fully-qualified name of this archetype, e.g. rerun.archetypes.Points2D.

fn indicator() -> MaybeOwnedComponentBatch<'static>

Creates a ComponentBatch out of the associated Self::Indicator component.

fn required_components() -> Cow<'static, [ComponentName]>

Returns the names of all components that must be provided by the user when constructing this archetype.

fn recommended_components() -> Cow<'static, [ComponentName]>

Returns the names of all components that should be provided by the user when constructing this archetype.

fn optional_components() -> Cow<'static, [ComponentName]>

Returns the names of all components that may be provided by the user when constructing this archetype.

fn all_components() -> Cow<'static, [ComponentName]>

Returns the names of all components that must, should and may be provided by the user when constructing this archetype.

fn from_arrow_components( arrow_data: impl IntoIterator<Item = (ComponentName, Box<dyn Array>)> ) -> DeserializationResult<Self>

Given an iterator of Arrow arrays and their respective ComponentNames, deserializes them into this archetype.

fn from_arrow( data: impl IntoIterator<Item = (Field, Box<dyn Array>)> ) -> Result<Self, DeserializationError>

where Self: Sized,

Given an iterator of Arrow arrays and their respective field metadata, deserializes them into this archetype.

impl AsComponents for DisconnectedSpace

fn as_component_batches(&self) -> Vec<MaybeOwnedComponentBatch<'_>>

Exposes the object’s contents as a set of ComponentBatchs.

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

Serializes all non-null Components of this bundle into Arrow arrays.

impl Clone for DisconnectedSpace

fn clone(&self) -> DisconnectedSpace

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for DisconnectedSpace

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

Formats the value using the given formatter.

impl PartialEq for DisconnectedSpace

fn eq(&self, other: &DisconnectedSpace) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl SizeBytes for DisconnectedSpace

fn heap_size_bytes(&self) -> u64

Returns the total size of self on the heap, in bytes.

fn is_pod() -> bool

Is Self just plain old data?

fn total_size_bytes(&self) -> u64

Returns the total size of self in bytes, accounting for both stack and heap space.

fn stack_size_bytes(&self) -> u64

Returns the total size of self on the stack, in bytes.

impl Copy for DisconnectedSpace

impl Eq for DisconnectedSpace
