Struct Line 

pub struct Line { /* private fields */ }

Component for a line entity — the physical path an elevator car travels.

In a building this is a hoistway/shaft. For a space elevator it is a tether or cable. The term “line” is domain-neutral.

A line belongs to exactly one GroupId at a time but can be reassigned at runtime (swing-car pattern). Multiple cars may share a line (multi-car shafts); collision avoidance is left to game hooks.

Intrinsic properties only — relationship data (which elevators, which stops) lives in LineInfo on the ElevatorGroup.

Implementations

impl Line

pub fn name(&self) -> &str

Human-readable name.

pub const fn group(&self) -> GroupId

Dispatch group this line currently belongs to.

pub const fn orientation(&self) -> Orientation

Physical orientation.

pub const fn position(&self) -> Option<&FloorPosition>

Optional floor-plan position.

pub const fn min_position(&self) -> f64

Lowest reachable position along the line axis.

pub const fn max_position(&self) -> f64

Highest reachable position along the line axis.

pub const fn max_cars(&self) -> Option<usize>

Maximum number of cars allowed on this line.

Trait Implementations

impl Clone for Line

fn clone(&self) -> Line

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Line

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Line

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Serialize for Line

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl WorldQuery for &Line

type Item<'w> = &'w Line

The item yielded per entity.

fn fetch(world: &World, id: EntityId) -> Option<Self::Item<'_>>

Try to fetch data for a single entity. Returns None if missing.

fn contains(world: &World, id: EntityId) -> bool

Check component presence without extracting data.
