snake.mrd_utils.utils

Utils for the MRD format.

Module Contents

Classes

ACQ	Acquisition flags of MRD as an IntFlags.

Functions

get_waveform_id	Generate a unique id from an input string.
obj2b64encode	Return the base64 encoded pickle of a python object.
b64encode2obj	Load a base64 string as a python object.

API

snake.mrd_utils.utils.get_waveform_id(input_string: str) → int

Generate a unique id from an input string.

The generated id is guaranteed to be bigger than 1024 and smaller than 2^16.

Parameters:

input_string (str) – The input string from which to generate the unique id.

Returns:

Unique id generated from the input string.

Return type:

int

Examples

>>> generate_unique_id('hello_world')
32767
>>> generate_unique_id('this_is_a_test')
20481

snake.mrd_utils.utils.obj2b64encode(f: Any) → bytes

Return the base64 encoded pickle of a python object.

snake.mrd_utils.utils.b64encode2obj(s: str) → Any

Load a base64 string as a python object.
