Enum IfcBooleanOperator 

pub enum IfcBooleanOperator {
    Union,
    Intersection,
    Difference,
}

IfcBooleanOperator: the three set operations IFC defines.

The IFC-file enumeration is distinct from the neutral operator, with an explicit lossless conversion at the adapter boundary under lowering.

The link is feature-gated because the target crate is optional; naming it unconditionally breaks cargo doc --no-default-features. See axiolid_core::BooleanOperator.

Variants

Union

.UNION. – everything in either operand.

Intersection

.INTERSECTION. – everything in both operands.

Difference

.DIFFERENCE. – first operand minus second. Not commutative; swapping the operands of a clipping result deletes the wall instead of the opening.

Implementations

impl IfcBooleanOperator

pub fn parse(token: &str) -> Option<Self>

Parse an enumeration token, with or without its surrounding dots.

Accepts any case because STEP keywords are case-insensitive and real exporters are inconsistent about it.

pub fn as_token(self) -> &'static str

The EXPRESS token, without dots.

pub fn is_order_sensitive(self) -> bool

Does operand order change the result?

Only DIFFERENCE is order-sensitive, and it is also the most common operator in building models, so a walker that normalises operand order for caching must check this first.
