Struct InverseAttribute 

#[non_exhaustive]
pub struct InverseAttribute {
    pub name: String,
    pub redeclares: Option<String>,
    pub entity: String,
    pub for_attribute: String,
    pub aggregation: Option<Aggregation>,
}

One INVERSE attribute: Name : SET [0:1] OF Entity FOR Attribute;.

Inverse attributes occupy no Part 21 slot; they state how many instances of entity may point at this one through for_attribute.

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.

name: String

Declared name, unqualified.

redeclares: Option<String>

The supertype named when a subtype redeclares an inherited inverse (SELF\X.Name : ...); None for a new inverse attribute.

entity: String

The entity whose attribute points back at this one.

for_attribute: String

The attribute named after FOR, as written.

aggregation: Option<Aggregation>

SET or BAG with its bounds; None for a single-valued inverse.

Implementations

impl InverseAttribute

pub fn new( name: impl Into<String>, entity: impl Into<String>, for_attribute: impl Into<String>, ) -> Self

pub fn redeclaring(self, supertype: impl Into<String>) -> Self

Marks the inverse a redeclaration of supertype’s.

pub fn with_aggregation(self, aggregation: Aggregation) -> Self

Makes the inverse an aggregate (SET or BAG).
