Rusqlite Migrate
Simple schema migration tool for rusqlite using user_version instead of an SQL table to maintain the current schema version.
2021-03-13: multiline migrations may quietly fail, due to #2. This is being worked on.
Benefit
Simplicity
There is a set of SQL statements and you just append to it to change the schema.
Speed
No need to add a table to be parsed, the user_version field is at a fixed offset in the sqlite file format.
Example
Please see examples/quick_start.rs.
