dd defd�Z� xZS )�Versiona> A class for comparing versions.
Implemented as a named tuple with all ordering methods. Comparisons
between X.Y.N and X.Y always treats the more specific number as larger.
:param major: the most significant number in a version
:param minor: next greatest significant number after major
:param patch: next greatest significant number after minor
:param rev: the least significant number in a version
:raises TypeError: If invalid arguments are given.
:raises ValueError: If invalid arguments are given.
Examples:
>>> Version(2, 9) == Version.from_str("2.9")
True
>>> Version(2, 9, 1) > Version.from_str("2.9.1")
False
>>> Version(3, 10) > Version.from_str("3.9.9.9")
True
>>> Version(3, 7) >= Version.from_str("3.7")
True

If the log level is too high due to the version boundary, log at DEBUG
level. Useful to add new warnings to previously unguarded code without
disrupting stable downstreams.

logged.
:param deprecated: Noun to be deprecated. Write this as the start
of a sentence, with no period. Version and extra message will
be appended.
:param deprecated_version: The version in which the thing was
deprecated
:param extra_message: A remedy for the user's problem. A good
message will be actionable and specific (i.e., don't use a
generic "Use updated key." if the user used a deprecated key).
End the string with a period.
:param schedule: Manually set the deprecation schedule. Defaults to
5 years. Leave a comment explaining your reason for deviation if
setting this value.
:param skip_log: Return log text rather than logging it. Useful for
running prior to logging setup.
:return: NamedTuple containing log level and log message
DeprecationLog(level: int, message: str)
