Enum LevelMatch 

pub enum LevelMatch {
    Elevation {
        tolerance_metres: f64,
    },
    Name,
}

axioval:derived.same-level: levels of different sources that stand for one federated level, such as the architecture model’s and the MEP model’s storeys at one elevation.

Unlike a Derivation it needs no geometry: a capability matches two containers it has already climbed to by what their sources state, their elevation or their name, so it is never routed to a geometry provider. Parameters follow the name as for a derivation: by is elevation (the default) or name, and tolerance (metres, default 0, elevation only) is the largest elevation difference of one level. A container is always on its own level; two containers of one source never share one.

Variants

Elevation

Elevations at most tolerance_metres apart.

Fields

tolerance_metres: f64

Largest elevation difference of one level, in metres.

Name

Names that are equal as stated.

Implementations

impl LevelMatch

pub fn parse( relationship: &str, ) -> Result<Option<Self>, RelationshipSelectionError>

The level match a relationship identity names, None for any other identity.

Errors

RelationshipSelectionError::InvalidRequest for a malformed, unknown or repeated parameter, a negative or non-finite tolerance, or a tolerance with by=name.

pub fn same(&self, left: &LevelFacts, right: &LevelFacts) -> Option<bool>

Whether two levels of different sources are one level: None when either does not state what the match compares.

Elevations compare with the rounding of one unit conversion allowed beyond the tolerance, so levels stated as 3000 mm and 3 m match with none.
