The data can be stored not only in memory, but also on disk and remains persistent between application runs. \n\n## How to install:\n```bash\npip install call-once\n```\n\n## How to use:\nLook to test directory to get idea. Code is compatible with python >= 3.4\n\n### Simple example\n```python\nimport CallOnce\nfrom CallOnce.Enums import ArgumentsMode\n\n\n@CallOnce.CallOnce(args_mode=ArgumentsMode.SERIALIZE_AND_HASH)\ndef plus_one(value):\n    print (\"Function invoked for {}\".format(value))\n    return value + 1\n\nprint(plus_one(5))\nprint(plus_one(5))\nprint(plus_one(10))\n\n# Function invoked for 5\n# 6\n# 6\n# Function invoked for 10\n# 11\n```\n\n### Example with TTL\n```python\nfrom datetime import timedelta\nimport CallOnce\n\n@CallOnce.CallOnce(ttl=timedelta(milliseconds=100))\ndef plus_one(value):\n    print (\"Function invoked for {}\".format(value))\n    return value + 1\n\nprint(plus_one(5))\nprint(plus_one(5))\nfrom time import sleep\nsleep(0.5)\nprint(plus_one(5))\nprint(plus_one(5))\n\n# Function invoked for 5\n# 6\n# Function invoked for 5\n# 6\n```\n\n\n## What are arguments of decorator?\n##### args_mode\n* ArgumentsMode.SERIALIZE_AND_HASH - Arguments of invocation are hashed \n* ArgumentsMode.IGNORE - Arguments are ignored and result of first invocation is cashed (Default)\n\n##### hash_mode\n* HashFunction.PYTHON - Standard Python Hash function is in use (Default)\n* HashFunction.MD5 - MD5\n\n##### ttl\nObject of type datetime.timedelta that defines for how long given result should be cache. If None than we will remember it forever. \nDefault is None\n\n\n## ToDo:\n* Improve tests for dictionary mode\n* Add Serialisation and persistent storage on hard drive\n\n\n\n\n\n\n",
