Struct Segment 

Source 
pub struct Segment<'a> { /* private fields */ }
Expand description

A Segment represents a bundle of adjacent Lanes which share a continuously traversable road surface. Every LanePosition on a given Lane of a Segment has a corresponding LanePosition on each other Lane, all with the same height-above-surface h, that all map to the same GeoPoint in 3-space.

Segments are grouped by Junction.

Implementations§

Source§

impl<'a> Segment<'a>

Source

pub fn id(&self) -> String

Returns the id of the Segment. The id is a unique identifier for the Segment within the RoadGeometry.

§Returns

A String containing the id of the Segment.

Source

pub fn junction(&self) -> Result<Junction<'_>, MaliputError>

Returns the Junction to which this Segment belongs.

§Returns

An Result<Junction, MaliputError> containing the Junction to which this Segment belongs. If the Segment does not belong to a Junction, an error is returned.

Source

pub fn num_lanes(&self) -> i32

Returns the number of lanes in the Segment.

§Returns

The number of lanes in the Segment.

Source

pub fn lane(&self, index: i32) -> Result<Lane<'_>, MaliputError>

Returns the lane at the given index.

§Arguments
  • index - The index of the lane to retrieve.
§Returns

A Lane containing the lane at the given index.
