TypeClinic.__call__(hint, /, *, fail_fast=False)[source]

Given a hint (a type and/or generic alias), return a ClinicResult object describing the result of the check.

Parameters:: fail_fast – If True, return on first failure. If False, all failures are discovered and reported.

TypeClinic.check(hint, /, *, fail_fast=False)[source]

Given a hint (a type and/or generic alias), raise a ClinicError exception describing the result of the check if an error is found.

Parameters:: fail_fast – If True, return on first failure. If False, all failures are discovered and reported.

>>> f = sf.Frame.from_fields(((10, 2, 8, 3), (False, True, True, False), ('1517-01-01', '1517-04-01', '1517-12-31', '1517-06-30')), columns=('a', 'b', 'c'), dtypes=dict(c=np.datetime64), name='x')

>>> tc = sf.TypeClinic((f, True))
>>> tc.check(tuple[bool, bool])
ClinicError('\nIn tuple[bool, bool]\n└── Expected bool, provided Frame invalid')

TypeClinic.warn(hint, /, *, fail_fast=False, category=<class 'UserWarning'>)[source]

Given a hint (a type and/or generic alias), issue a warning describing the result of the check if an error is found.

Parameters:

fail_fast – If True, return on first failure. If False, all failures are discovered and reported.
category – The Warning subclass to be used for issueing the warning.
