This package adds Pydantic support to sortedcontainers, a fast pure-Python library for sorted mutable collections.
It implements Pydantic's special methods on subclasses of sortedcontainer's SortedDict, SortedList, and SortedSet classes so that you can use them with Pydantic's models, validation, and serialization. To use, simply import the respective class of the same name from sortedcontainers_pydantic instead of from sortedcontainers. Only Pydantic V2 is supported.
from pydantic import BaseModel, TypeAdapter
from sortedcontainers_pydantic import SortedList
class MyModel(BaseModel):
sorted_list: SortedList[int]
MyModel(sorted_list=[3, 1, 2])
#> MyModel(sorted_list=SortedList([1, 2, 3]))
MyModel.model_validate_json('{"sorted_list": [3, 1, 2]}')
#> MyModel(sorted_list=SortedList([1, 2, 3]))
MyModel(sorted_list=[3, 1, 2]).model_dump_json()
#> '{"sorted_list":[1,2,3]}'
TypeAdapter(SortedList).validate_python([3, 1, 2])
#> SortedList([1, 2, 3])
TypeAdapter(SortedList).validate_json("[3, 1, 2]")
#> SortedList([1, 2, 3])Reproducible example created by reprexlite v0.5.0
