Major internal refactor: AcBinarySerializer and BinarySerializationContext are now generic on TOutput : BinaryOutputBase, enabling JIT devirtualization and eliminating virtual dispatch in hot serialization loops. All serialization logic (WriteValue, WriteObject, WriteArray, etc.) is now generic on TOutput and delegates buffer operations to the output instance (ArrayBinaryOutput or BufferWriterBinaryOutput). Context pooling is now per output type. All buffer management is moved to output classes. The public API is unchanged, but the internal architecture is now fully generic and ready for further JIT optimizations. Also disables the source generator and sets UseMetadata=false by default.
Refactored serialization for performance:
- Precompute type metadata (primitive, collection, element info) in TypeMetadataBase
- Remove runtime type caches from JsonUtilities
- Rewrite primitive/collection checks to use direct logic or metadata
- Update scan pass and serialization hot path to use wrappers/metadata
- Improve buffer management (halve oversized buffers)
- Increase profiler warmup iterations, comment out deserialization in hot path
- Clean up code and clarify documentation/comments
Reduces runtime overhead and memory usage, streamlines hot path execution.
Refactored AcBinarySerializer to assign cache indices immediately upon detecting duplicates during the scan pass, eliminating the need for a separate post-processing step. Updated TryTrack methods to take a ref nextCacheIndex for inline assignment. Removed AssignCacheIndicesInOrder and related code, simplified string interning, and made RegisterMetadataType static. This reduces allocations and improves performance by making cache index assignment a single-pass operation.
Refactor binary serializer to use a true two-pass process for string interning and object reference tracking. Adds a scan pass to identify duplicates and assigns cache indices deterministically in first-occurrence order. Updates wire format to write explicit cache indices after *First markers. Refactors InternEntry, removes marker rewriting, and updates deserializer to match new format. Improves performance, correctness, and robustness for complex object graphs with shared references and repeated strings.
