Contains traits responsible for the actual construction of SQL statements

The types in this module are part of Diesel’s public API, but are generally only useful for implementing Diesel plugins. Applications should generally not need to care about the types inside of this module.

Re-exports

pub use self::bind_collector::BindCollector;

Modules

Types related to managing bind parameters during query construction.

Structs

The primary type used when walking a Diesel AST during query execution.

A struct that implements fmt::Display and fmt::Debug to show the SQL representation of a query.

Represents a SQL DELETE statement.

The structure returned by insert_into.

A fully constructed insert statement.

The return value of sql_query.

Represents a complete UPDATE statement.

Traits

Types which can be passed to update.set.

Types that can be converted into a complete, typed SQL query.

A type which can be passed to update or delete.

A complete SQL query with a return type.

Constructs a SQL query from a Diesel AST.

An untyped fragment of SQL.

Uniquely identifies queries by their type for the purpose of prepared statement caching.

Indicates that a type is a SELECT statement.

Marker trait to indicate that no additional operations have been added to a record for insert.

Functions

Takes a query QueryFragment expression as an argument and returns a type that implements fmt::Display and fmt::Debug to show the query.

Type Definitions

A DELETE statement with a boxed WHERE clause

An UPDATE statement with a boxed WHERE clause.

A specialized Result type used with the query builder.

The type returned by update. The only thing you can do with this type is call set on it.
