Module shadow 

Shadow Postgres backends.

ShadowBackend is the trait every backend implements. Two concrete backends ship in v0.2:

• testcontainers: boots a fresh container via the testcontainers crate. Hermetic; requires Docker. Default when Docker is present.
• dsn: connects to a user-supplied Postgres via a DSN. Useful for developers without Docker, for projects with extensions that need pre-installed binaries, and for managed-PG environments.

Modules

testcontainers
