Notable Features and Bug Fixes:
-
PR 370: Add
SimpleValuetype to more fully support CBOR Simple Values, including values not unassigned by IANA and... -
PR 376: Add
ByteStringtype to support CBOR maps with byte string keys because Go doesn't allow []byte as map keys and... -
PR 342: Add
DecOptions.UTF8to decode invalid UTF-8. Default is unchanged (reject invalid UTF-8 and return error). -
PR 377: Add
EncOptions.NilContainersModeto encode nil Go maps and slices as CBOR nil (default) or empty container. -
PR 381: Add
Decoder.Skip()to skip CBOR data item in CBOR Sequences (RFC 8742). -
PR 379: Make
Decoder.Decode()returnio.ErrUnexpectedEOFinstead ofio.EOFon EOF if current CBOR data item is incomplete. -
PR 380: Make
Unmarshal()andValid()returnio.ErrUnexpectedEOF(instead of ignoring extraneous data if any remain). -
PR 382: Return buffer to pool in
Encode(). Some overhead inEncode()for a lot more efficientNewEncoder().Encode().
Benchmarks that use NewEncoder() for each call to Encode() will improved speed and memory. Benchmarks that reuse same Encoder will see some smaller overhead as the tradeoff.
