Overview

Parses a Flight wire byte string into an ordered array of row records.

Used by the structural Flight matchers to assert on parsed semantics rather than literal bytes. Pure function — no I/O, no global state, no Thread.current.

Examples:

wire = "1:I[\"/L.jsx\",\"L\",[\"/L.jsx\"]]\n0:[\"$\",\"$L1\",null,{}]\n"
Ruact::Testing::FlightWireParser.parse(wire)
# => [
#      { id: 1, class: :import, payload: ["/L.jsx", "L", ["/L.jsx"]], raw: "1:I...\n" },
#      { id: 0, class: :model,  payload: ["$", "$L1", nil, {}],       raw: "0:[\"$\"...\n" }
#    ]
