Struct StationOffset 

#[non_exhaustive]
pub struct StationOffset<'c> { /* private fields */ }

An offset of one base piece, measured in its own length; see the module documentation.

Implementations

impl<'c> StationOffset<'c>

pub fn new( base: StationPiece<'c>, law: OffsetLaw, ) -> Result<StationOffset<'c>, GeomError>

The offset of base by law.

Errors

A base that is itself an offset, a base span with a seam of its curve strictly inside it, a planar law on a 3D base, a non-finite law or a zero reference direction, each by name.

pub fn base(&self) -> StationPiece<'c>

The base piece.

pub fn law(&self) -> OffsetLaw

The law.

pub fn convention(&self) -> DistanceConvention

The convention the offset is measured in: its base’s (plan distance beside an elevated or banked curve, arc length beside any other).

pub fn length(&self) -> Result<f64, GeomError>

The offset’s own length in its convention, from its start.

Errors

The refusals of the module documentation, and the base’s evaluators’.
