Struct diesel::expression::sql_literal::SqlLiteral

pub struct SqlLiteral<ST> { /* fields omitted */ }

Available for when you truly cannot represent something using the expression DSL. You will need to provide the type of the expression, in addition to the SQL. The compiler will be unable to verify the correctness of this type.
