Pack Named

1 Version

Wraps a structurally-typed stream unwrapped_named_type into its named-type identity named_type, producing a strongly-typed alias from its underlying representation. Type-level relabel only; inverse of unpack_named.

How it fits

Typical backends

Reconstruct a named value after editing its fields, then ship it as JSON.

Coerce a raw tuple into a named event for a consumer that requires the alias.

Caveats

Hard constraintThe input's structural shape must match the named type's declared body exactly; a mismatch is rejected by type inference at build time, not at runtime.
I/O contractPurely a type-level relabel: no fields are added or dropped, no data is copied or reshaped, and output cadence matches input cadence one-to-one.
Hard constraintThe concrete named_type is fixed by the downstream wiring, so this step cannot be deployed in isolation without a consumer that pins the alias.
