Strawberry-graphql

--------------------

This release adds support for union with a single member, they are
useful for future proofing your schema in cases you know a field
will be part of a union in future.

python
import strawberry

from typing import Annotated


strawberry.type
class Audio:
duration: int


strawberry.type
class Query:
note: Python's Union type doesn't support single members,
Union[Audio] is exactly the same as Audio, so we use
use Annotated and strawberry.union to tell Strawberry this is
a union with a single member
latest_media: Annotated[Audio, strawberry.union("MediaItem")]


schema = strawberry.Schema(query=Query)

This release fixes a bug where returning a generic type from a field
that was returning an interface would throw an error.

--------------------

Improve the time complexity of `strawberry.interface` using `resolve_type`.
Achieved time complexity is now O(1) with respect to the number of
implementations of an interface. Previously, the use of `is_type_of` resulted
in a worst-case performance of O(n).
