provider()

This is liable to change in the future.

Creates a declared provider 'constructor'. The return value of this function can be used to create "struct-like" values. Example:

data = provider() d = data(x = 2, y = 3) print(d.x + d.y) # prints 5

Arguments

• doc (defaults to '') A description of the provider that can be extracted by documentation generating tools.
• fields (defaults to None) If specified, restricts the set of allowed fields.
  Possible values are:
  • list of fields:
    

    provider(fields = ['a', 'b'])

  • dictionary field name -> documentation:
    

    provider( fields = { 'a' : 'Documentation for a', 'b' : 'Documentation for b' })

  All fields are optional.
