schemer-rusqlite: Missing instructions or automated initialization: no such table: _schemer

[nathan-at-least]

In my application when I run the migration example in the crate docs, I get an error with "no such table: _schemer", so either the docs are skipping a step or if the API is intended to function as documented, there is a bug.

The anyhow::Error displayed by my unit test looks like this:

Error: An error occurred while interacting with the adapter.

Caused by:
    0: no such table: _schemer
    1: Error code 1: SQL error or missing database

Note, this same error is triggered by the literal doc example which is demonstrated in #21 which ensures the doc example is executed by automated testing.
