Detailed Description

Lightweight representation of LHAPDF / SLHA-style identifiers.

This header defines the LhaID struct, a small utility type used to encode identifiers that may be composed of several integer components (e.g. PDG-like IDs, block indices, etc.).

The representation is essentially a vector of long integers, with helpers to:

• construct from integers, initializer lists, vectors or strings,
• serialize to a compact string form (e.g. "1_2_3"),
• compare and hash IDs for use in associative containers.
