Module block_tools::db::use_diesel::prelude[−][src]

Re-exports important traits and types. Meant to be glob imported when using Diesel.

Structs

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

Enums

ConnectionError

Errors which can occur during Connection::establish

Traits

AppearsOnTable	Indicates that all elements of an expression are valid given a from clause.
BelongingToDsl	Constructs a query that finds record(s) based on directional association with other record(s).
BoolExpressionMethods	Methods present on boolean expressions
BoxableExpression	Helper trait used when boxing expressions.
Column	A column on a database table. Types which implement this trait should have been generated by the `table!` macro.
Connection	A connection to a database
EscapeExpressionMethods	Adds the `escape` method to `LIKE` and `NOT LIKE`. This is used to specify the escape character for the pattern.
Expression	Represents a typed fragment of SQL.
ExpressionMethods	Methods present on all expressions, except tuples
GroupByDsl	This trait is not yet part of Diesel's public API. It may change in the future without a major version bump.
GroupedBy	The `grouped_by` function groups records by their parent.
Identifiable	This trait indicates that a struct represents a single row in a database table.
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.
IntoSql	Converts a type to its representation for use in Diesel's query builder.
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.
NullableExpressionMethods	Methods present on all expressions
OptionalExtension	See the method documentation.
PgArrayExpressionMethods	PostgreSQL specific methods present on array expressions.
PgExpressionMethods	PostgreSQL specific methods which are present on all expressions.
PgSortExpressionMethods	PostgreSQL expression methods related to sorting.
PgTextExpressionMethods	PostgreSQL specific methods present on text expressions.
PgTimestampExpressionMethods	PostgreSQL specific methods present on timestamp expressions.
QueryDsl	Methods used to construct select statements.
QuerySource	Represents a type which can appear in the `FROM` clause. Apps should not need to concern themselves with this trait.
Queryable	Trait indicating that a record can be queried from the database.
RunQueryDsl	Methods used to execute queries.
SaveChangesDsl	Sugar for types which implement both `AsChangeset` and `Identifiable`
SelectableExpression	Indicates that an expression can be selected from a source.
Table	A SQL database table. Types which implement this trait should have been generated by the `table!` macro.
TextExpressionMethods	Methods present on text expressions

Type Definitions

ConnectionResult	A specialized result type for establishing connections.
QueryResult	A specialized result type for queries.
