Struct rerun::components::HalfSize2D

#[repr(transparent)]
pub struct HalfSize2D(pub Vec2D);

Component: Half-size (radius) of a 2D box.

Measured in its local coordinate system.

The box extends both in negative and positive direction along each axis. Negative sizes indicate that the box is flipped along the respective axis, but this has no effect on how it is displayed.

Implementations

impl HalfSize2D

pub const fn new(half_width: f32, half_height: f32) -> HalfSize2D

Create a new half-extent from half-width and half-height.

pub fn width(self) -> f32

Width of a box using this half-extent.

pub fn height(self) -> f32

Height of a box using this half-extent.

pub fn box_min(self, box_center: Position2D) -> Vec2

Returns the min position of a box with these half-extents and a given center.

In “image space axis semantics” (y-axis points down, x-axis points right), this is the top-left corner.

pub fn box_max(self, box_center: Position2D) -> Vec2

Returns the maximum of a box with these half-extents and a given center.

In “image space axis semantics” (y-axis points down, x-axis points right), this is the bottom-right corner.

Methods from Deref<Target = Vec2D>

pub const ZERO: Vec2D = _

pub const ONE: Vec2D = _

pub fn x(&self) -> f32

The x-coordinate, i.e. index 0.

pub fn y(&self) -> f32

The y-coordinate, i.e. index 1.

impl<T> From<T> for HalfSize2D

where T: Into<Vec2D>,

fn from(v: T) -> HalfSize2D

Converts to this type from the input type.

impl Loggable for HalfSize2D

type Name = ComponentName

fn name() -> <HalfSize2D as Loggable>::Name

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

fn arrow_datatype() -> DataType

The underlying arrow2::datatypes::DataType, excluding datatype extensions.

fn to_arrow_opt<'a>( data: impl IntoIterator<Item = Option<impl Into<Cow<'a, HalfSize2D>>>> ) -> Result<Box<dyn Array>, SerializationError>

where HalfSize2D: Clone + 'a,

Given an iterator of options of owned or reference values to the current Loggable, serializes them into an Arrow array.

fn from_arrow_opt( arrow_data: &(dyn Array + 'static) ) -> Result<Vec<Option<HalfSize2D>>, DeserializationError>

where HalfSize2D: Sized,

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