pub enum DirectionSense {
    Positive,
    Negative,
}

Negative

NEGATIVE: the layer/profile direction runs opposite the reference axis.

Implementations

impl DirectionSense

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

Parses an IfcDirectionSenseEnum token (case-insensitively). Returns None for any string that is not POSITIVE or NEGATIVE.

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

The IfcDirectionSenseEnum token for this value.

Inverse of Self::parse; kept adjacent so the two cannot drift.
