What's Changed

• Improved Serialization by @seandstewart in https://github.com/seandstewart/typical/pull/190

Full Changelog: https://github.com/seandstewart/typical/compare/v2.7.11...v2.8.0

What's Changed

• CPython 3.9.8+ and 3.10.1+ have new logic for type resolution of ForwardRefs which caused a regression in our runtime type analysis. This change adds handling for this new logic.

This release fixes a regression in our serializer factory which failed to account for optional/nullable enum types when dumping to a primitive, leading to an AttributeError when attempting to access the enum value.

sqlite3.Row objects are C extension types which meet the contract for a mapping, but do not evaluate as a subclass of the Mapping generic. This change adds them to our list of "mapping-compliant" types.

NamedTuple objects were improperly treated as a simple builtin subtype when coercing user-defined types, which resulted in unexpected behavior. This fixes deserialization logic to use the standard translator protocol for named tuples.

Derived classes of a typic.klass object were improperly recognized as a simple Iterable.

This caused a recursion error when attempting to serialize these objects, since the __iter__ magic method relies upon the iterator factory, but the iterator factory simply called the __iter__ magic method.

Resolves #185

Fixes

• #183

Misc

• Expose always param in the @typic.al decorator.

Fixes:

• Support collections.deque as Array constraint (resolves #181)
• Fix union constraints generation on stable py3.10 release.

Misc:

• Extend DSN support for sqlite urls.

Fixes

• Nested mappings with exactly two keys could be improperly deserialized (#179)
• Early return with stdlib get_tojson meant we weren't properly bootstrapping docs.

Improvements

• asyncpg.Record objects are now recognized as a Mapping type.

Enhancements

• typical will now default to orjson for json serialization and deserialization if it is installed. This provides up to 3X performance boost, but has different behavior and output than ujson or stdlib json.
• Callable class instances are now treated as function types when wrapped (thank you @xbanke, #173)

Fixes

• Expose the always parameter to typic.klass, since we are raising warnings about its usage (#177)

Features

• Wrapped routines and frozen dataclasses now coerce inputs up to 10x faster than before (on-par with wrapped classes or bound protocols) (#175).
• More descriptive and correct type-hints for the public API.
• Type-hinting with an abstract base class (ABC) will now result in validation against that type rather than coercion (#170)

Fixes

• Resolves issue where we'd sometimes fail to clean up the repr of subscripted generics (#170)
• Resolves issue where we failed to locate the correct target type for a value within a Union of overlapping types (#170)
• Resolves issue where we'd iterate over the fields of a non-iterable, primitive type when coercing to a collection, rather than raise a TypeError as expected (#174).

Fixes

• Add intelligent instance-checks for unions (resolves #167)
• Make field.default positional (resolves #168)
• Add __version__ to typic.__init__ and add bumpver to manage multiple versions (resolves #168)

Fixes

• This release resolves an issue when building serializers for Unions of pandas collection types (e.g., DataFrame, Series) which prevented proper compilation (#166)

Changes

• Tagged Unions must be tagged with "public" fields (e.g., no fields starting with _ are considered).

Fixes

• Fixes dynamic evaluation of serializers for unknown types within containers.

Features

• Support un-tagged, "Generic" Unions (e.g., Union[int, str]) (#19, docs)
• Basic support for Callable types (#159)

Misc

• Re-worked handler dispatch in deserializer builder.
• More idiomatic implementation of delayed SerdeProtocols

Features

• This release adds support for Python @ 3.10.0rc1 (#162)

Bugfixes

• Fix resolution of env-var aliases.
• Use lazy iterator factory when we can't guess the type.
