Implementations

impl DatasetMetadata

pub fn new<P: Into<String>, A: Into<String>>( p4_names: Vec<P>, aux_names: Vec<A>, ) -> LadduResult<Self>

Construct metadata from explicit particle and auxiliary names.

pub fn empty() -> Self

Create metadata with no registered names.

pub fn p4_index(&self, name: &str) -> Option<usize>

Resolve the index of a four-momentum by name.

pub fn p4_names(&self) -> &[String]

Registered four-momentum names in declaration order.

pub fn aux_index(&self, name: &str) -> Option<usize>

Resolve the index of an auxiliary scalar by name.

pub fn aux_names(&self) -> &[String]

Registered auxiliary scalar names in declaration order.

pub fn p4_selection(&self, name: &str) -> Option<&P4Selection>

Look up a resolved four-momentum selection by name (canonical or alias).

pub fn add_p4_alias<N>( &mut self, alias: N, selection: P4Selection, ) -> LadduResult<()>

where N: Into<String>,

Register an alias mapping to one or more existing four-momenta.

pub fn add_p4_aliases<I, N>(&mut self, entries: I) -> LadduResult<()>

where I: IntoIterator<Item = (N, P4Selection)>, N: Into<String>,

Register multiple aliases at once.
