Enum SubqueryExpressionKind 

#[non_exhaustive]
pub enum SubqueryExpressionKind {
    Exists,
    Count,
    Collect,
}

The value produced by a subquery expression.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.
