Struct rerun::Quaternion

pub struct Quaternion(pub [f32; 4]);

Datatype: A Quaternion represented by 4 real numbers.

Note: although the x,y,z,w components of the quaternion will be passed through to the datastore as provided, when used in the viewer Quaternions will always be normalized.

Tuple Fields

0: [f32; 4]

Trait Implementations

impl Clone for Quaternion

fn clone(&self) -> Quaternion

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Quaternion

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

Formats the value using the given formatter.

impl Default for Quaternion

fn default() -> Quaternion

Returns the “default value” for a type.

impl From<[f32; 4]> for Quaternion

fn from(xyzw: [f32; 4]) -> Quaternion

Converts to this type from the input type.

impl From<Quat> for Quaternion

fn from(q: Quat) -> Quaternion

Converts to this type from the input type.

impl From<Quaternion<f32>> for Quaternion

fn from(val: Quaternion<f32>) -> Quaternion

Converts to this type from the input type.

impl From<Quaternion> for [f32; 4]

fn from(value: Quaternion) -> [f32; 4]

Converts to this type from the input type.

impl From<Quaternion> for Quat

fn from(q: Quaternion) -> Quat

Converts to this type from the input type.

impl From<Quaternion> for Rotation3D

fn from(q: Quaternion) -> Rotation3D

Converts to this type from the input type.

impl Loggable for Quaternion

type Name = DatatypeName

fn name() -> <Quaternion 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, Quaternion>>>> ) -> Result<Box<dyn Array>, SerializationError>

where Quaternion: 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 + 'static) ) -> Result<Vec<Option<Quaternion>>, DeserializationError>

where Quaternion: 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 Quaternion

fn eq(&self, other: &Quaternion) -> 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 PartialOrd for Quaternion

fn partial_cmp(&self, other: &Quaternion) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

This method tests less than (for self and other) and is used by the < operator.

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

This method tests less than or equal to (for self and other) and is used by the <= operator.

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

This method tests greater than (for self and other) and is used by the > operator.

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

This method tests greater than or equal to (for self and other) and is used by the >= operator.

impl SizeBytes for Quaternion

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.
