strata_protocol/dynamic_json

Convert gleam/dynamic.Dynamic values back into gleam/json.Json so frames decoded into the typed sum types (which carry payloads as Dynamic) can be re-encoded to bytes for round-trip and proxying.

This is a deliberately public part of strata_protocol's API (not internal/): both strata_server and strata_client need to turn a decoded frame's Dynamic payload back into Json, and this module is the single, shared place that does it — neither package should reimplement the walk below.

Mirrors the pattern in beryl/wire. Handles strings, ints, floats, bools, nil, lists, and string-keyed dicts. Falls back to json.null() for anything else (e.g., tuples, atoms) — the protocol contract is JSON values only.

Functions

dynamic_to_json

Convert a Dynamic (decoded from JSON) back into json.Json.

Total, not partial: every input produces a Json value, falling back to json.null() for shapes that cannot occur in JSON (tuples, atoms, records). That fallback is only safe because every Dynamic this function is called on originates from json.parse/decode.dynamic somewhere upstream (a server or client frame decoder) — callers must not feed it Dynamic built from arbitrary in-memory data.
