v0.12.0

Refactor the underlying implementation to prepare for further development

New features

• Add Binary, LargeBinary, FixedSizeBinary(n), FixedSizeList(n) support for arrow2
• Add support to serialize / deserialize bool from integer arrays
• Add a helper to construct Bool8 arrays
• Include the path of the field that caused an error in the error message
• Include backtrace information only for the debug representations of errors

API changes

• Use impl serde::Serialize instead of &(impl serde::Serialize + ?Sized)
• Use &[FieldRef] instead of &[Field] in arrow APIs

Removed deprecated API

• Remove serde_arrow::schema::Schema
• Remove serde_arrow::ArrowBuilder and serde_arrow::Arrow2Builder
• Remove from_arrow_fields / to_arrow_fields for SerdeArrowSchema, use the TryFrom conversions to convert between fields and SerdeArrowSchema
• Remove SerdeArrowSchema::new(), Overwrites::new()

v0.11.7

• Fix tracing of JSON mixing nulls with non-null data

v0.11.6

• Add arrow=52 support
• Add support for Binary, LargeBinary (only arrow)
• Add support for FixedSizeBinary(n) (only arrow>=47)
• Add support for FixedSizeList(n) (only arrow)
• Add support to overwrite field definitions with TracingOptions::overwrite
• Add support to serialize enums without data (e.g., enum E { A, B, C}) as strings by setting the corresponding field to a string value (Utf, LargeUtf, Dictionary(_, Utf8), Dictionary(_, LargeUtf8)
• Allow to trace enums without data as dictionary encoded strings by setting enums_without_data_as_strings to true in TracingOptions

v0.11.5

• Add serde_arrow::Serializer
• Add support for new type wrappers, tuples and tuple structs to serde_arrow::Deserializer
• Add a generic serde_arrow::ArrayBuilder with support for both arrow and arrow2
• Implement TryFrom<&[Field]> (arrow and arrow2) and TryFrom<&[FieldRef]> (arrow only) for SerdeArrowSchema
• Implement TryFrom<&SerdeArrowSchema> for Vec<Field> and Vec<FieldRef> for arrow

v0.11.4

• Add serde_arrow::Deserializer

v0.11.3

• Support for serializing/deserializing timestamps with second, microsecond, and nanosecond encoding.
• Fixed (de)serialization of fractional seconds.

Thanks

The following people contributed to this release:

• @ryzhyk added string support for timestamps with non-millisecond units, fixed the handling of fractional seconds (PR)

v0.11.2

• Support Duration(unit)
• Rewrite data type parsing with stricter parsing

v0.11.1

• Support Timestamp(Second, tz), Timestamp(Millisecond, tz), Timestamp(Nanosecond, tz). At the moment only (de)serialization from / to integers is supported for non-microsecond units
• Support Time32(unit)
