Struct Layer 

pub struct Layer<DB: Marker, E> { /* private fields */ }

A tower_layer::Layer that enables the Tx extractor.

This layer adds a lazily-initialised transaction to the request extensions. The first time the Tx extractor is used on a request, a connection is acquired from the configured sqlx::Pool and a transaction is started on it. The same transaction will be returned for subsequent uses of Tx on the same request. The inner service is then called as normal. Once the inner service responds, the transaction is committed or rolled back depending on the status code of the response.
