Trait Implementations

impl ArrowDeserialize for Point2D

type ArrayType = Point2DArray

The arrow2::Array type corresponding to this field

fn arrow_deserialize<'a>(v: Option<Self>) -> Option<Self>

Deserialize this field from arrow

impl ArrowField for Point2D

type Type = Point2D

This should be Self except when implementing large offset and fixed placeholder types. For the later, it should refer to the actual type. For example when the placeholder type is LargeString, this should be String.

fn data_type() -> DataType

The DataType

impl ArrowSerialize for Point2D

type MutableArrayType = MutablePoint2DArray

The arrow2::array::MutableArray that holds this value

fn new_array() -> Self::MutableArrayType

Create a new mutable array

fn arrow_serialize(v: &Self, array: &mut Self::MutableArrayType) -> Result<()>

Serialize this field to arrow

impl Clone for Point2D

fn clone(&self) -> Point2D

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Point2D

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

Formats the value using the given formatter.

impl<'a> From<&'a Point2D> for Cow<'a, Point2D>

fn from(value: &'a Point2D) -> Self

Converts to this type from the input type.

impl From<[f32; 2]> for Point2D

fn from(p: [f32; 2]) -> Self

Converts to this type from the input type.

impl<'a> From<Point2D> for Cow<'a, Point2D>

fn from(value: Point2D) -> Self

Converts to this type from the input type.

impl From<Point2D> for Vec2

fn from(pt: Point2D) -> Self

Converts to this type from the input type.

impl From<Point2D> for Vec3

fn from(pt: Point2D) -> Self

Converts to this type from the input type.

impl From<Vec2> for Point2D

fn from(pt: Vec2) -> Self

Converts to this type from the input type.

impl LegacyComponent for Point2D

fn legacy_name() -> ComponentName

The name of the component.

fn field() -> Field

Create a Field for this LegacyComponent.

impl Loggable for Point2D

type Name = ComponentName

type Item<'a> = <&'a <Point2D as ArrowDeserialize>::ArrayType as IntoIterator>::Item

type Iter<'a> = <&'a <Point2D as ArrowDeserialize>::ArrayType as IntoIterator>::IntoIter

fn name() -> Self::Name

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

fn to_arrow_datatype() -> DataType

The underlying arrow2::datatypes::DataType.

fn try_to_arrow_opt<'a>( data: impl IntoIterator<Item = Option<impl Into<Cow<'a, Self>>>>, _extension_wrapper: Option<&str> ) -> SerializationResult<Box<dyn Array>>where Self: Clone + 'a,

Given an iterator of options of owned or reference values to the current Loggable, serializes them into an Arrow array. The Arrow array’s datatype will match Loggable::to_arrow_datatype.

fn try_iter_from_arrow( data: &dyn Array ) -> DeserializationResult<Self::Iter<'_>>where Self: Sized,

Given an Arrow array, deserializes it into a iterator of Loggable::Items.

fn to_arrow<'a>( data: impl IntoIterator<Item = impl Into<Cow<'a, Self>>>, extension_wrapper: Option<&str> ) -> Box<dyn Array, Global>where Self: Clone + 'a,

Given an iterator of owned or reference values to the current Loggable, serializes them into an Arrow array. The Arrow array’s datatype will match Loggable::to_arrow_datatype.

fn try_to_arrow<'a>( data: impl IntoIterator<Item = impl Into<Cow<'a, Self>>>, extension_wrapper: Option<&str> ) -> Result<Box<dyn Array, Global>, SerializationError>where Self: Clone + 'a,

Given an iterator of owned or reference values to the current Loggable, serializes them into an Arrow array. The Arrow array’s datatype will match Loggable::to_arrow_datatype.

fn try_from_arrow_opt( data: &(dyn Array + 'static) ) -> Result<Vec<Option<Self>, Global>, DeserializationError>

Given an Arrow array, deserializes it into a collection of optional Loggables.

impl PartialEq<Point2D> for Point2D

fn eq(&self, other: &Point2D) -> 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.
