Local database support

[drodil]

As it is very painful to keep the beer, hops and yeast data in Rust structs, find out if there is optional solution to store this data inside the executable/lib. For example file based database that could travel inside the package. See #23 #39 #41 #42 for use cases of this.

Personally, I would just add data files in JSON/YAML format and load them when required with serde.

Pros:

• easily editable/contributable
• tiny amount of code required to load
• fits the existing data structures (a big vec of data)

Cons:

• will take slightly longer to load all data data from disk than if we were querying data as needed from a proper database if we include it as a string inline at compile time, it will just be the time to parse the string into a struct which is negligible.

If you think that's an okay solution, I'll start working on it.

that sounds good actually, please go ahead.

Sounds like a good idea! Just wondering about the packaging of the json for the rustybeer library; is it possible to do somehow so that the users of the library have the same data available? Don't have that much of experience about that so please enlighten me! :)
