Struct re_types::datatypes::TranslationAndMat3x3

pub struct TranslationAndMat3x3 {
    pub translation: Option<Vec3D>,
    pub mat3x3: Option<Mat3x3>,
    pub from_parent: bool,
}

Datatype: Representation of an affine transform via a 3x3 affine matrix paired with a translation.

First applies the matrix, then the translation.

Fields

translation: Option<Vec3D>

3D translation, applied after the matrix.

mat3x3: Option<Mat3x3>

3x3 matrix for scale, rotation & shear.

from_parent: bool

If true, this transform is from the parent space to the space where the transform was logged.

If false (default), the transform maps from this space to its parent, i.e. the translation is the position in the parent space.

Implementations

impl TranslationAndMat3x3

pub const IDENTITY: Self = _

The identity transform, representing no translation or rotation.

pub fn new<T: Into<Vec3D>, M: Into<Mat3x3>>(translation: T, mat3x3: M) -> Self

Create a new TranslationAndMat3x3 from a translation and a 3x3 matrix.

pub fn from_translation<T: Into<Vec3D>>(translation: T) -> Self

Create a new TranslationAndMat3x3 with just the translation.

pub fn from_mat3x3<M: Into<Mat3x3>>(mat3x3: M) -> Self

Create a new TranslationAndMat3x3 with just the 3x3 matrix.

pub fn from_parent(self) -> Self

Indicate that this transform is from parent to child. This is the oppositve of the default, which is from child to parent.

Trait Implementations

impl Clone for TranslationAndMat3x3

fn clone(&self) -> TranslationAndMat3x3

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for TranslationAndMat3x3

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

Formats the value using the given formatter.

impl Default for TranslationAndMat3x3

fn default() -> Self

Returns the “default value” for a type.

impl<'a> From<&'a TranslationAndMat3x3> for Cow<'a, TranslationAndMat3x3>

fn from(value: &'a TranslationAndMat3x3) -> Self

Converts to this type from the input type.

impl<'a> From<TranslationAndMat3x3> for Cow<'a, TranslationAndMat3x3>

fn from(value: TranslationAndMat3x3) -> Self

Converts to this type from the input type.

impl From<TranslationAndMat3x3> for Transform3D

fn from(v: TranslationAndMat3x3) -> Self

impl Loggable for TranslationAndMat3x3

type Name = DatatypeName

fn name() -> Self::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, Self>>>> ) -> 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::arrow_field.

fn from_arrow_opt( arrow_data: &dyn Array ) -> DeserializationResult<Vec<Option<Self>>>

where Self: Sized,

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

fn extended_arrow_datatype() -> DataType

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

fn arrow_field() -> Field

The underlying arrow2::datatypes::Field, including datatype extensions.

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

where Self: '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::arrow_field.

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

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

impl PartialEq for TranslationAndMat3x3

fn eq(&self, other: &TranslationAndMat3x3) -> 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 TranslationAndMat3x3

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.
