Struct RestFrame 

pub struct RestFrame { /* private fields */ }

Rest-frame transform for a parent four-momentum.

Sequential-decay builders start from lab-frame event vectors, then apply one rest-frame transform per vertex. Each child vertex receives four-vectors that have already been transformed into its parent’s rest frame.

Implementations

impl RestFrame

pub fn new(parent: Vec4) -> LadduResult<Self>

Construct a rest-frame transform for parent.

pub const fn parent(self) -> Vec4

Return the parent four-momentum.

pub const fn boost(self) -> Vec3

Return the boost vector into the parent rest frame.

pub fn transform(self, momentum: Vec4) -> Vec4

Transform a four-momentum into the parent rest frame.

pub fn momentum(self, momentum: Vec4) -> Vec3

Transform a four-momentum into the parent rest frame and return its three-momentum.

Trait Implementations

impl Clone for RestFrame

fn clone(&self) -> RestFrame

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RestFrame

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for RestFrame

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for RestFrame

fn eq(&self, other: &RestFrame) -> 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 Serialize for RestFrame

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Copy for RestFrame

impl StructuralPartialEq for RestFrame
