Quickstart
Building a Test Dataclass

... field1: int
... field2: str
... field3: float | None
Writing
>>> from tempfile import NamedTemporaryFile
>>> from typeline import TsvWriter
>>>
>>> temp_file = NamedTemporaryFile(mode="w+t", suffix=".tsv")
>>>
>>> with TsvWriter.from_path(temp_file.name, MyData) as writer:
... writer.write_header()
... writer.write(MyData(10, "test1", 0.2))
... writer.write(MyData(20, "test2", None))
Reading
>>> from typeline import TsvReader
>>>
>>> with TsvReader.from_path(temp_file.name, MyData) as reader:
... for record in reader:
... print(record)
