Example

Simple batch of 2D arrows

fn main() -> Result<(), Box<dyn std::error::Error>> {
    let rec = rerun::RecordingStreamBuilder::new("rerun_example_arrow2d").spawn()?;

    rec.log(
        "arrows",
        &rerun::Arrows2D::from_vectors([[1.0, 0.0], [0.0, -1.0], [-0.7, 0.7]])
            .with_radii([0.025])
            .with_origins([[0.25, 0.0], [0.25, 0.0], [-0.1, -0.1]])
            .with_colors([[255, 0, 0], [0, 255, 0], [127, 0, 255]])
            .with_labels(["right", "up", "left-down"]),
    )?;

    Ok(())
}

Fields

vectors: Vec<Vector2D>

All the vectors for each arrow in the batch.

origins: Option<Vec<Position2D>>

All the origin (base) positions for each arrow in the batch.

If no origins are set, (0, 0) is used as the origin for each arrow.

radii: Option<Vec<Radius>>

Optional radii for the arrows.

The shaft is rendered as a line with radius = 0.5 * radius. The tip is rendered with height = 2.0 * radius and radius = 1.0 * radius.

colors: Option<Vec<Color>>

Optional colors for the points.

labels: Option<Vec<Text>>

Optional text labels for the arrows.

class_ids: Option<Vec<ClassId>>

Optional class Ids for the points.

The class ID provides colors and labels if not specified explicitly.

Implementations

impl Arrows2D

pub fn with_origins( self, origins: impl IntoIterator<Item = impl Into<Position2D>> ) -> Arrows2D

Trait Implementations

impl Archetype for Arrows2D

type Indicator = GenericIndicatorComponent<Arrows2D>

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>)> ) -> Result<Arrows2D, DeserializationError>

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 Arrows2D

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>

impl Clone for Arrows2D

fn clone(&self) -> Arrows2D

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Arrows2D

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

Formats the value using the given formatter.

impl PartialEq for Arrows2D

fn eq(&self, other: &Arrows2D) -> 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 Arrows2D

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
