Lua.VM.Display.Closure (Lua v1.0.0-rc.0)

Display wrapper for a Lua closure ({:lua_closure, proto, upvalues}) returned across the Lua.eval!/2 boundary.

Carries the closure's source, line, and arity for human display. The wrap fires in both decode: true and decode: false modes because raw closure tuples have always leaked to the user.

Fields

:source — source name attached to the closure's prototype (for example "<eval>" or "my_script.lua").
:line — first line of the closure's body, derived from the prototype's :lines field.
:arity — the number of declared parameters. Variadic closures have :arity equal to the fixed-parameter count; the variadic flag is reflected by appending +... in the inspect output.
:vararg? — true when the closure accepts varargs (...).
:ref — the original {:lua_closure, proto, upvalues} tuple so callers can still reach the live closure (for example via Lua.call_function/3).

Internal pattern matches against {:lua_closure, _, _} are unaffected; the wrap is a display affordance applied at the eval boundary only.
