class_docstr: A function declaration expression.
  
  Parameters
  ----------
  params: List[tvm.relay.Var]
      List of input parameters to the function.
  
  body: tvm.relay.Expr
      The body of the function.
  
  ret_type: Optional[tvm.relay.Type]
      The return type annotation of the function.
  
  type_params: Optional[List[tvm.relay.TypeParam]]
      The additional type parameters, this is only
      used in advanced usecase of template functions.
  
  span: Optional[tvm.relay.Span]
      Span that points to original source code.
docstr: Get the text format of the expression.
  
  Parameters
  ----------
  show_meta_data : bool
      Whether to include meta data section in the text
      if there is meta data.
  
  annotate: Optional[Object->str]
      Optionally annotate function to provide additional
      information in the comment block.
  
  Returns
  -------
  text : str
      The text format of the expression.
  
  Notes
  -----
  The meta data section is necessary to fully parse the text format.
  However, it can contain dumps that are big (e.g constant weights),
  so it can be helpful to skip printing the meta data section.
