Trait Implementations

impl Clone for Scalar

fn clone(&self) -> Scalar

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Scalar

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

Formats the value using the given formatter.

impl Display for Scalar

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

Formats the value using the given formatter.

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

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

Converts to this type from the input type.

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

fn from(value: Scalar) -> Self

Converts to this type from the input type.

impl From<Scalar> for f64

fn from(value: Scalar) -> Self

Converts to this type from the input type.

impl From<f64> for Scalar

fn from(value: f64) -> Self

Converts to this type from the input type.

impl Loggable for Scalar

type Name = ComponentName

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 from_arrow(arrow_data: &dyn Array) -> DeserializationResult<Vec<Self>>

where Self: Sized,

Given an Arrow array, deserializes it into a collection of 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>>> ) -> SerializationResult<Box<dyn Array>>

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.

impl PartialEq for Scalar

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

fn partial_cmp(&self, other: &Scalar) -> 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 Zeroable for Scalar

fn zeroed() -> Self

Calls zeroed.

impl Copy for Scalar
