os-traits 0.2.0

A library containing standardized trait strings

A library containing standardized trait strings.

Traits are strings that represent a feature of some resource provider. This library contains the catalog of constants that have been standardized in the OpenStack community to refer to a particular hardware, virtualization, storage, network, or device trait.

Usage

os-traits is primarily composed of a set of constants that may be referenced by simply importing the os_traits module and referencing one of the module’s traits constants:

$ python
Python 2.7.11+ (default, Apr 17 2016, 14:00:29)
[GCC 5.3.1 20160413] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import os_traits as ot
>>> print ot.HW_CPU_X86_SSE42
HW_CPU_X86_SSE42

Don’t know what the symbol names are for the os_traits module? There’s a helper method for that:

>>> import pprint
>>> pprint.pprint(ot.get_symbol_names())
