0.12.3

• Add arrow=54 support

0.12.2

Bug fixes:

• Fixed deserialization from sliced arrays (#248). Note that the current solution requires up front work when constructing the array deserializers, as described in the issue. The removal of the performance penalty is tracked in (#250)

Thanks

• @jkylling for reporting (#248) and for discussing potential solutions

0.12.1

New features

• Add support for various jiff types (jiff::Date, jiff::Time, jiff::DateTime, jiff::Timestamp, jiff::Span, jiff::SignedDuration)
• Add support for tracing lists as List instead of LargeList by setting sequence_as_large_list to false in TracingOptions
• Add support for tracing strings and strings in dictionaries as Utf8 instead of LargeUtf8 by setting strings_as_large_utf8 to false in TracingOptions
• Add support to auto-detect dates (2024-09-30, mapped to Date32) and times (12:00:00, mapped to Time64(Nanosecond))) in from_samples
• Improved error messages for non self describing types (chrono::*, uuid::Uuid, std::net::IpAddr)

Thanks

The following people contributed to this release:

• @jkylling added support for tracing lists as List and strings as Utf8

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()
