Structs

MysqlConnection	A connection to a MySQL database. Connection URLs should be in the form mysql://[user[:password]@]host/database_name
PgConnection	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
SqliteConnection	Connections for the SQLite backend. Unlike other backends, "connection URLs" for SQLite are file paths or special identifiers like :memory.

Traits

BelongingToDsl	Constructs a query that finds record(s) based on directional association with other record(s).
GroupedBy	The grouped_by function groups records by their parent.
Insertable	Represents that a structure can be used to insert a new row into the database. This is automatically implemented for &[T] and &Vec<T> for inserting more than one record.
JoinOnDsl	Specify the ON clause for a join statement. This will override any implicit ON clause that would come from joinable!
JoinTo	Indicates that two tables can be joined without an explicit ON clause.
SaveChangesDsl	Sugar for types which implement both AsChangeset and Identifiable
