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: AsRef<[usize]>>(constituents: T) -> Self

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 duplicate 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

Formats the value using the given formatter.

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

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for Mass

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

Formats the value using the given formatter.

impl Serialize for Mass

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Variable for Mass

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

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

fn value_on_local(&self, dataset: &Dataset) -> Vec<Float>

This method distributes the Variable::value method over each Event in a Dataset (non-MPI version).

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

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

fn eq(&self, val: Float) -> VariableExpression

where Self: Sized + 'static,

Create an VariableExpression that evaluates to self == val

fn lt(&self, val: Float) -> VariableExpression

where Self: Sized + 'static,

Create an VariableExpression that evaluates to self < val

fn gt(&self, val: Float) -> VariableExpression

where Self: Sized + 'static,

Create an VariableExpression that evaluates to self > val

fn ge(&self, val: Float) -> VariableExpression

where Self: Sized + 'static,

Create an VariableExpression that evaluates to self >= val

fn le(&self, val: Float) -> VariableExpression

where Self: Sized + 'static,

Create an VariableExpression that evaluates to self <= val
