Struct re_log_types::NumInstances

#[repr(transparent)]
pub struct NumInstances(pub u32);

Explicit number of instances in a crate::DataRow.

Component batches in that row should have a length of either this number, zero (clear) or one (splat).

Tuple Fields

0: u32

Implementations

impl NumInstances

pub fn get(self) -> u32

Trait Implementations

impl Clone for NumInstances

fn clone(&self) -> NumInstances

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for NumInstances

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

Formats the value using the given formatter.

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

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

Converts to this type from the input type.

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

fn from(value: NumInstances) -> Self

Converts to this type from the input type.

impl From<NumInstances> for u32

fn from(val: NumInstances) -> Self

Converts to this type from the input type.

impl From<u32> for NumInstances

fn from(value: u32) -> Self

Converts to this type from the input type.

impl Loggable for NumInstances

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: '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 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.

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

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

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

impl Ord for NumInstances

fn cmp(&self, other: &NumInstances) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized + PartialOrd,

Restrict a value to a certain interval.

impl PartialEq for NumInstances

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

fn partial_cmp(&self, other: &NumInstances) -> 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 NumInstances

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.

impl Zeroable for NumInstances

fn zeroed() -> Self

Calls zeroed.
