Struct OwnedEvent 

pub struct OwnedEvent { /* private fields */ }

Owned metadata-aware event data.

This is useful for detached events, MPI fetches, and Python-owned event objects. Use OwnedEvent::as_event to evaluate variables and amplitudes through the standard borrowed Event interface.

Implementations

impl OwnedEvent

pub fn new(event: Arc<EventData>, metadata: Arc<DatasetMetadata>) -> Self

Create a new metadata-aware event from raw data and dataset metadata.

pub fn data(&self) -> &EventData

Borrow the raw EventData.

pub fn data_arc(&self) -> Arc<EventData>

Obtain a clone of the underlying EventData handle.

pub fn as_event(&self) -> Event<'_>

Borrow this owned row as an Event suitable for variable and amplitude evaluation.

pub fn p4s(&self) -> IndexMap<&str, Vec4>

Return the four-momenta stored in this event keyed by their registered names.

pub fn aux(&self) -> IndexMap<&str, f64>

Return the auxiliary scalars stored in this event keyed by their registered names.

pub fn weight(&self) -> f64

Return the event weight.

pub fn metadata(&self) -> &DatasetMetadata

Retrieve the dataset metadata attached to this event.

pub fn metadata_arc(&self) -> Arc<DatasetMetadata>

Clone the metadata handle associated with this event.

pub fn p4(&self, name: &str) -> Option<Vec4>

Retrieve a four-momentum (or aliased sum) by name.

pub fn get_p4_sum<N>(&self, names: N) -> Vec4

where N: IntoIterator, N::Item: AsRef<str>,

Return a four-momentum formed by summing four-momenta with the specified names.

pub fn boost_to_rest_frame_of<N>(&self, names: N) -> EventData

where N: IntoIterator, N::Item: AsRef<str>,

Boost all four-momenta into the rest frame defined by the specified particle names.

Methods from Deref<Target = EventData>

pub fn get_p4_sum<T: AsRef<[usize]>>(&self, indices: T) -> Vec4

Return a four-momentum from the sum of four-momenta at the given indices in the EventData.

pub fn boost_to_rest_frame_of<T: AsRef<[usize]>>(&self, indices: T) -> Self

Boost all the four-momenta in the EventData to the rest frame of the given set of four-momenta by indices.
