14 The HttpRepo[C, R, U] class is a mixin class that provides a common set of methods for CRUD operations. 

15 This class is intended to be used in a composition pattern where a class has a mixin property. For example: 

16 

17 ``` 

18 class MyClass: 

19 def __init__(self, repo, logger): 

20 self.mixins = HttpRepo(repo, logger)
