data_store

Documentation

Overview

Package data_store provides data store functionality. The data store is kept in memory, but optionally the data store may be saved to a file to provide a perisistent data store. This uses go-cache (https://github.com/pmylund/go-cache) for storing the data.

The methods that set, get, and delete key/value pairs also take a `key_type` argument that specifies what kind of object it is.
