Module encoder 

Zero-copy Protobuf encoder for Qdrant gRPC protocol.

This module implements direct wire format encoding without intermediate struct allocations. Key optimizations:

• Pre-computed field tag bytes
• Buffer reuse via BytesMut
• Direct memcpy for vectors (no per-element loop)

Functions

encode_create_collection_proto

Encode CreateCollection request to protobuf wire format.

encode_delete_collection_proto

Encode DeleteCollection request.

encode_delete_points_proto

Encode a DeletePoints request.

encode_search_proto

Encode a SearchPoints request directly to protobuf wire format.

encode_upsert_proto

Encode an UpsertPoints request to protobuf wire format.

encode_varint

Encode a varint (variable-length integer) into the buffer. Uses 7 bits per byte, MSB indicates continuation.

encode_varint_u64

Encode a u64 varint.

encode_with_payload_true

Encode with_payload = true as a sub-message.
