Database

Creates a Database Layer which requires an existing ConnectionSource.

A Connection which is incapable of running anything, to use when unit testing (and the queries are actually stubbed, so they do not need a Database). Trying to run actual queries against it will fail.

Provides that ZIO with a Connection. All DB action in the ZIO will be auto-committed. Failures in the initial ZIO will be wrapped in a Right in the error case of the resulting ZIO, with connection errors resulting in a failure with the exception wrapped in a Left.

This method should be implemented by subclasses, to provide the connection.

As autoCommit, but errors when handling the connections are treated as defects instead of failures.

As autoCommitOrDie, for ZStream instances instead of ZIO instances.

As autoCommit, but exceptions are simply widened to a common failure type. The resulting failure type is a superclass of both DbException and the error type of the inital ZIO.

As autoCommitOrWiden, for ZStream instances instead of ZIO instances.

As autoCommit, for ZStream instances instead of ZIO instances.

This method should be implemented by subclasses, to provide the connection.

As fromDatasource, but provides a default ErrorStrategiesRef. When a method is called with no available implicit ErrorStrategiesRef, the ErrorStrategiesRef in argument will be used.

Commodity method: creates a Database Layer which includes its own ConnectionSource based on a DataSource. Most connection pool implementations should be able to provide you a DataSource.

When no implicit ErrorStrategies is available, the default ErrorStrategies will be used.

As fromDatasource(ErrorStrategiesRef), but an ErrorStrategies is provided through a layer instead of as a parameter.

A Database which is incapable of running anything, to use when unit testing (and the queries are actually stubbed, so they do not need a Database). Trying to run actual queries against it will fail.

Provides that ZIO with a Connection. A transaction will be opened before any actions in the ZIO, and closed after. It will commit only if the ZIO succeeds, and rollback otherwise. Failures in the initial ZIO will be wrapped in a Right in the error case of the resulting ZIO, with connection errors resulting in a failure with the exception wrapped in a Left.

As transactionOrDie, for ZStream instances instead of ZIO instances.
