Conversation
Adds serde round-trip support to RTCConfiguration using W3C camelCase field names (iceServers, iceTransportPolicy, bundlePolicy, rtcpMuxPolicy, peerIdentity, iceCandidatePoolSize). All dependent types already had serde derives (RTCIceServer, RTCBundlePolicy, RTCIceTransportPolicy, RTCRtcpMuxPolicy, RTCSdpSemantics). Certificates are excluded via #[serde(skip)] because they contain private-key material. Use RTCCertificate::serialize_pem() / from_pem() to persist certificates separately. Adds test_configuration_json_round_trip to replace the previously commented-out Go test with a Rust equivalent. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

Pull request overview
Note
Copilot was unable to run its full agentic suite in this review.
This PR adds opt-in Serde support for RTCConfiguration to enable JSON/JavaScript interoperability, and introduces a JSON round-trip test to validate camelCase serialization/deserialization.
Changes:
- Derives
Serialize/DeserializeforRTCConfigurationwithcamelCasefield naming. - Skips
certificatesduring serialization/deserialization to avoid persisting private-key material. - Replaces an old commented TODO with a working JSON round-trip test.
💡 Add Copilot custom instructions for smarter, more guided reviews. Learn how to get started.

RTCConfiguration is a “dictionary”-style config where most JSON keys are typically optional, but Deserialize without #[serde(default)] will fail if any non-Option fields are missing from input JSON. Consider adding #[serde(default)] at the struct level (or per-field defaults) so deserializing partial configs (e.g., only iceServers) behaves as expected and matches typical WebRTC config usage.

The PR description says Serde support is “opt-in” behind a serde feature gate, but this diff adds unconditional serde imports/derives and an unconditional serde_json test. If the feature really is meant to be optional, gate the import, derives, and the test with cfg(feature = "serde") / cfg_attr(feature = "serde", derive(...)) (and similarly for the serde attributes) so builds without the feature don’t fail.

The test’s contains(...) assertions are brittle (they can pass even if JSON structure is wrong, and can fail due to unrelated formatting/ordering changes). Prefer parsing into serde_json::Value and asserting specific keys/values (e.g., iceServers[0].urls[0], plus iceTransportPolicy, bundlePolicy, rtcpMuxPolicy) to precisely validate camelCase naming and structure.
