Struct RelationExistsComparator 

#[non_exhaustive]
pub struct RelationExistsComparator {
    pub eq: Option<bool>,
    pub neq: Option<bool>,
}

Comparator asserting the existence (or absence) of a relation.

Fields (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.

eq: Option<bool>

The relation exists.

neq: Option<bool>

The relation does not exist.
