Struct PostgresMigrator 

pub struct PostgresMigrator;

Applies the immutable OxideBatch PostgreSQL migration set.

Implementations

impl PostgresMigrator

pub const fn supported_schema_version() -> u32

Returns the schema version installed by this crate.

pub async fn installed_schema_version( config: &PostgresConfig, ) -> Result<Option<u32>, RepositoryError>

Reads the installed schema version without changing it.

This is the read-only counterpart of PostgresMigrator::migrate. It takes no advisory lock, applies no migration, and creates no schema, so an unprivileged operator identity can report migration state. An uninitialized schema is reported as None rather than as a failure, because “not yet migrated” is an answer rather than an outage.

Errors

Returns a redacted configuration or repository failure. The connection string, driver message, and SQL text are never included.

pub async fn migrate(config: &PostgresConfig) -> Result<(), RepositoryError>

Applies pending migrations under a database-scoped advisory lock.

This operation is intended for a dedicated migrator identity. Runtime repository startup only verifies the schema and never migrates it.

Errors

Returns a redacted configuration or repository failure. A newer schema is never changed.
