Module diesel::query_dsl

Traits that construct SELECT statements

Traits in this module have methods that generally map to the keyword for the corresponding clause in SQL, unless it conflicts with a Rust keyword (such as WHERE/where).

Methods for constructing queries lives on the QueryDsl trait. Methods for executing queries live on RunQueryDsl.

See also expression_methods and dsl.
