Struct survex_rs::data::SurveyData

pub struct SurveyData {
    pub stations: Vec<Rc<RefCell<Station>>>,
    pub graph: UnGraph<String, f64>,
}

Handles the creation and management of stations, as well as holding the graph of stations.

Fields

stations: Vec<Rc<RefCell<Station>>>

graph: UnGraph<String, f64>

Implementations

impl SurveyData

pub fn new() -> Self

Create an empty SurveyData instance with no stations or connections. This method should not be used directly. Instead, create a SurveyData instance from a Survex file using the load_from_path helper function.

pub fn get_by_label(&self, label: &str) -> Option<Rc<RefCell<Station>>>

Retrieve a reference to a Station by its label.

pub fn get_by_coords(&self, coords: &Point) -> Option<Rc<RefCell<Station>>>

Retrieve a reference to a Station by its coordinates. If multiple stations exist at the given coordinates, the first station found is returned.

pub fn add_or_update( &mut self, coords: Point, label: &str ) -> (Rc<RefCell<Station>>, NodeIndex)

This helper method is used to add or update a Station to both the stations vector and the graph.

If a Station with the given label already exists, the existing station is updated with the new coordinates. Otherwise, a new Station is created and added to the stations vector and the graph. In either case, a reference to the station is returned in a tuple along with the index of the station in the graph.

Trait Implementations

impl Default for SurveyData

fn default() -> Self

Returns an empty SurveyData instance with no stations.
