Examples & Code Migration Guide for Gocql

[steve-gray]

In terms of migrating code over to this, it'd be great if there were:

• Examples showing connections, queries being done.
• A quick bootstrap guide
• A few notes in the docs about the current level of API stability/what can be relied on to not change/any known omissions etc?

... in the README (and/or an examples folder).

The context being, we've just open sourced Charybdis, our solution for providing a generics-aware typed wrapper around gocql/gocqlx at https://github.com/zeroflucs-given/charybdis - and we'd be very, very keen to give this a look to swap out our underlying usage of gocql/gocqlx if its in a place where this can happen but not really sure where to start with it, or where the dragons might be.
