Module diesel::backend

Types which represent various database backends

Modules

• sql_dialect
  This module contains all options provided by diesel to configure the SqlDialect trait.

Traits

• Backend
  A database backend
• DieselReserveSpecialization
  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: …
• HasBindCollector
  The bind collector type used to collect query binds for this backend
• HasRawValue
  The raw representation of a database value given to FromSql.
• SqlDialect
  This trait provides various options to configure the generated SQL for a specific backend.
• TrustedBackend
  This trait just indicates that noone implements SqlDialect without enabling the i-implement-a-third-party-backend-and-opt-into-breaking-changes feature flag.

Type Aliases

• BindCollector
  A helper type to get the bind collector for a database backend. Equivalent to <DB as HasBindCollector<'a>>::BindCollector<'a>j
• RawValue
  A helper type to get the raw representation of a database type given to FromSql. Equivalent to <DB as Backend>::RawValue<'a>.
