Detailed Description

std::formatter specializations for parcel::ICell and parcel::cell_t.

Lets std::format("{}", cell) work on any cell. The empty spec calls to_string() (compact); the alt-form # flag calls to_formatted_string() (multi-line). Concrete cells derived from ICell are picked up via a constrained specialization.

Format specs supported on ICell / cell_t:

• {} — compact to_string()
• {:#} — multi-line to_formatted_string()
• {:j} — compact JSON via to_json().dump()
• {:j2} — pretty JSON via to_json().dump(2)
• {:k} — kind id only
