Struct rerun::datatypes::Mat3x3

pub struct Mat3x3(pub [f32; 9]);

Datatype: A 3x3 Matrix.

Matrices in Rerun are stored as flat list of coefficients in column-major order:

            column 0       column 1       column 2
       -------------------------------------------------
row 0 | flat_columns[0] flat_columns[3] flat_columns[6]
row 1 | flat_columns[1] flat_columns[4] flat_columns[7]
row 2 | flat_columns[2] flat_columns[5] flat_columns[8]

Tuple Fields

0: [f32; 9]

Flat list of matrix coefficients in column-major order.

impl Loggable for Mat3x3

type Name = DatatypeName

fn name() -> <Mat3x3 as Loggable>::Name

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, Mat3x3>>>> ) -> Result<Box<dyn Array>, SerializationError>

where Mat3x3: 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<Mat3x3>>, DeserializationError>

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

where Self: 'a,

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

impl PartialEq for Mat3x3

fn eq(&self, other: &Mat3x3) -> 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 Mat3x3

fn partial_cmp(&self, other: &Mat3x3) -> 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.

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.
