Enum VerticalSegmentType 

#[non_exhaustive]
pub enum VerticalSegmentType {
    ConstantGradient,
    CircularArc,
    ParabolicArc,
    Clothoid,
    UserDefined,
    NotDefined,
    Other(String),
}

IfcAlignmentVerticalSegmentTypeEnum member: the vertical curve law applied over one segment’s distance-along span.

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.

ConstantGradient

CONSTANTGRADIENT: a straight grade line (start_gradient == end_gradient up to rounding, no or zero radius_of_curvature). Lowers exactly.

CircularArc

CIRCULARARC: constant-radius vertical curve; requires radius_of_curvature. Lowers exactly, as the circle itself.

ParabolicArc

PARABOLICARC: parabolic vertical curve; requires radius_of_curvature. Lowers exactly.

Clothoid

CLOTHOID: a clothoid-law vertical transition. Refused by lowering: the segment states neither end curvature, so its law is undetermined.

UserDefined

USERDEFINED: an author-supplied law outside the enumerated set.

NotDefined

NOTDEFINED: no vertical segment kind was declared.

Other(String)

An enumeration token this crate does not recognise, preserved verbatim.
