Struct Mass

pub struct Mass(/* private fields */);

A struct for obtaining the mass of a particle by indexing the four-momenta of an event, adding together multiple four-momenta if more than one index is given.

Implementations

impl Mass

pub fn new<T>(constituents: T) -> Mass

where T: AsRef<[usize]>,

Create a new Mass from the sum of the four-momenta at the given indices in the Event’s p4s field.

Trait Implementations

impl Clone for Mass

fn clone(&self) -> Mass

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Mass

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Mass

fn deserialize<__D>( __deserializer: __D, ) -> Result<Mass, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Serialize for Mass

fn serialize<__S>( &self, __serializer: __S, ) -> Result<<__S as Serializer>::Ok, <__S as Serializer>::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Variable for Mass

fn value(&self, event: &Event) -> f64

This method takes an Event and extracts a single value (like the mass of a particle).

fn value_on(&self, dataset: &Arc<Dataset>) -> Vec<f64>

This method distributes the Variable::value method over each Event in a Dataset.
