Struct NetRelation 

pub struct NetRelation {
    pub id: String,
    pub from_netelement_id: String,
    pub to_netelement_id: String,
    pub position_on_a: u8,
    pub position_on_b: u8,
    pub navigable_forward: bool,
    pub navigable_backward: bool,
}

Represents a navigability connection between two track segments

A NetRelation defines whether trains can travel from one netelement to another. Navigability may be unidirectional (e.g., one-way track) or bidirectional.

Examples

use tp_lib_core::NetRelation;

// Bidirectional connection: trains can go from A to B and from B to A
let relation = NetRelation::new(
    "NR001".to_string(),
    "NE_A".to_string(),
    "NE_B".to_string(),
    1,  // position_on_a: end of A
    0,  // position_on_b: start of B
    true,   // A → B allowed
    true,   // B → A allowed
)?;

assert!(relation.is_bidirectional());

Fields

id: String

Unique identifier for this netrelation

from_netelement_id: String

ID of the source netelement (starting track segment)

to_netelement_id: String

ID of the target netelement (destination track segment)

position_on_a: u8

Position on netelementA where the connection applies (0 = start, 1 = end)

position_on_b: u8

Position on netelementB where the connection applies (0 = start, 1 = end)

navigable_forward: bool

Whether trains can navigate forward (from → to)

navigable_backward: bool

Whether trains can navigate backward (to → from)

Implementations

impl NetRelation

pub fn new( id: String, from_netelement_id: String, to_netelement_id: String, position_on_a: u8, position_on_b: u8, navigable_forward: bool, navigable_backward: bool, ) -> Result<Self, ProjectionError>

Create a new netrelation with validation

pub fn validate(&self) -> Result<(), ProjectionError>

Validate netrelation fields

pub fn is_navigable_forward(&self) -> bool

Check if navigation is allowed in forward direction (from → to)

pub fn is_navigable_backward(&self) -> bool

Check if navigation is allowed in backward direction (to → from)

pub fn is_bidirectional(&self) -> bool

Check if bidirectional (both directions navigable)

Trait Implementations

impl Clone for NetRelation

fn clone(&self) -> NetRelation

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for NetRelation

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for NetRelation

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for NetRelation

fn eq(&self, other: &NetRelation) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for NetRelation

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
