Serde

Introduction

A serde integration is gated behind the "serde" feature flag. It is slower, produces slightly larger output, and (by extension) is not compatible with the native bitcode::{Encode, Decode}.

Unsupported features

• enum's with #[serde(untagged)].
• Fields with #[serde(skip_serializing_if = ...)], #[serde(default)], etc.
• Types like serde_json::Value, which internally serialize different types (numbers, arrays, etc.) without a normal enum discriminant.

Compatibility notes

• The serde version omits the flowinfo and scope_id fields of std::net::SocketAddrV6, but native bitcode keeps them.
