Struct Subtraction 

#[non_exhaustive]
pub struct Subtraction {
    pub opening: EntityId,
    pub relation: EntityId,
    pub body: NodeId,
    pub result: NodeId,
}

One opening removed from a host, with the nodes that express it.

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.

opening: EntityId

The voiding element (IfcOpeningElement, IfcVoidingFeature, …).

relation: EntityId

The IfcRelVoidsElement that authored the subtraction.

body: NodeId

The opening’s lowered Body, placed in world space.

result: NodeId

The host with this opening and every earlier one removed.
