CIEnum

class deepfos.lib.utils.CIEnum(value)

大小写非敏感的枚举类

经常用于入参为一组可选字符串的情况。 可以简化参数检查逻辑代码的书写。 当入参不支持时，提供友好的报错提示。

>>> class Flag(CIEnum):
...     zero = 'zero'
...     negative = 'negative'
...     positive = 'positive'
>>> def example(flag: Union[Flag, str]):
...     flag = Flag[flag]
...     if flag is Flag.zero:
...         return '0'
...     elif flag is Flag.negative:
...         return '-'
...     else:
...         return '+'
>>> example('zero')
'0'
>>> example('Zero')
'0'
>>> example(Flag.negative)
'-'
>>> example('unknown')
Traceback (most recent call last):
...
KeyError: "Flag: 'unknown' is not valid. Possible choices are: [zero, negative, positive]"
