Struct Model

pub struct Model {
    pub pois: BTreeMap<String, Poi>,
    pub poi_types: HashMap<String, PoiType>,
}

A data structure used for exporting and importing data to and from file.

Fields

pois: BTreeMap<String, Poi>

A list of POIs.

Could have been a hashmap…

poi_types: HashMap<String, PoiType>

A map of PoiType, indexed by their id.

We use a hashmap to list poi types, as the main purpose is to search for a PoiType based on its id. (Poi only stores the type’s id)

Implementations

impl Model

pub fn try_from_path<P: AsRef<Path>>(path: P) -> Result<Model>

Creates a new model based on data found in path.

pub fn save_to_path<P: AsRef<Path>>(&self, path: P) -> Result<()>

Saves the model to file.

pub fn try_merge(self, rhs: Model) -> Result<Model>

Tries to merge a Model into another.

Trait Implementations

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

Formats the value using the given formatter.

impl Default for Model

fn default() -> Model
