Struct VideoTimestamp

pub struct VideoTimestamp(pub i64);

Datatype: Presentation timestamp within a archetypes::AssetVideo.

Specified in nanoseconds. Presentation timestamps are typically measured as time since video start.

Tuple Fields

0: i64

Presentation timestamp value in nanoseconds.

impl Loggable for VideoTimestamp

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.

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 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.

impl Ord for VideoTimestamp

fn cmp(&self, other: &VideoTimestamp) -> 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,

impl PartialEq for VideoTimestamp

fn eq(&self, other: &VideoTimestamp) -> bool

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd for VideoTimestamp

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

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

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

Tests less than (for self and other) and is used by the < operator.

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

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

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

Tests greater than (for self and other) and is used by the > operator.

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

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

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.
