Struct diesel::expression::array_comparison::NotIn

#[non_exhaustive]
pub struct NotIn<T, U> { pub left: T, pub values: U, }
Expand description

Query dsl node that represents a left NOT IN (values) expression

Third party backend can customize the QueryFragment implementation of this query dsl node via SqlDialect::ArrayComparison. A customized implementation is expected to provide the same sematics as a ANSI SQL NOT IN expression.0

The postgres backend provided a specialized implementation by using left = ALL(values) as optimized variant instead.

Fields (Non-exhaustive)§

This struct is marked as non-exhaustive
Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.
§left: T

The expression on the left side of the NOT IN keyword

§values: U

The values clause of the NOT IN expression
