Traits

Backend

A database backend

DieselReserveSpecializationi-implement-a-third-party-backend-and-opt-into-breaking-changes

This is a marker trait which indicates that diesel may specialize a certain QueryFragment impl in a later version. If you as a user encounter, where rustc suggests adding this a bound to a type implementing Backend consider adding the following bound instead YourQueryType: QueryFragment<DB> (the concrete bound is likely mentioned by rustc as part of a note: …)

SqlDialect

This trait provides various options to configure the generated SQL for a specific backend.

TrustedBackendi-implement-a-third-party-backend-and-opt-into-breaking-changes

This trait just indicates that none implements SqlDialect without enabling the i-implement-a-third-party-backend-and-opt-into-breaking-changes feature flag.
