postgres_backend
only.Expand description
Provides types and functions related to working with PostgreSQL
Much of this module is re-exported from database agnostic locations. However, if you are writing code specifically to extend Diesel on PostgreSQL, you may need to work with this module directly.
Modules
Data structures for PG types which have no corresponding Rust type
PostgreSQL related query builder extensions
PostgreSQL specific SQL types
Structs
Represents DISTINCT ON (...)
i-implement-a-third-party-backend-and-opt-into-breaking-changes
This error indicates that a type lookup for a custom postgres type failed
The PostgreSQL backend
postgres
The connection string expected by PgConnection::establish
should be a PostgreSQL connection string, as documented at
https://www.postgresql.org/docs/9.4/static/libpq-connect.html#LIBPQ-CONNSTRING
i-implement-a-third-party-backend-and-opt-into-breaking-changes
Cache for the OIDs of custom Postgres types
i-implement-a-third-party-backend-and-opt-into-breaking-changes
The key used to lookup cached type oid’s inside of a PgMetadataCache.
The PostgreSQL query builder
The OIDs for a SQL type
Raw postgres value as received from the database
Used to build a transaction, specifying additional details.
Traits
i-implement-a-third-party-backend-and-opt-into-breaking-changes
Gets the PgMetadataCache
for a Connection<Backend=Pg>
so that the lookup of user defined types, or types which come from an extension can be cached.
Determines the OID of types at runtime
i-implement-a-third-party-backend-and-opt-into-breaking-changes
This is a helper trait to defer a type oid lookup to a later point in time
