Struct ActivityStore 

pub struct ActivityStore { /* private fields */ }

Storage for activity GPS data.

Provides efficient storage and retrieval of activity coordinates with support for bulk operations via flat buffers.

Implementations

impl ActivityStore

pub fn new() -> Self

Create a new empty activity store.

pub fn add( &mut self, id: String, coords: Vec<GpsPoint>, sport_type: String, ) -> Option<Bounds>

Add an activity with its GPS coordinates.

Returns the computed bounds for the activity.

pub fn add_flat( &mut self, id: String, flat_coords: &[f64], sport_type: String, ) -> Option<Bounds>

Add an activity from flat coordinate buffer.

Coordinates are [lat1, lng1, lat2, lng2, …].

pub fn add_many_flat( &mut self, activity_ids: &[String], all_coords: &[f64], offsets: &[u32], sport_types: &[String], ) -> Vec<String>

Add multiple activities from flat coordinate buffers.

This is the most efficient way to bulk-add activities from FFI.

pub fn remove(&mut self, id: &str) -> Option<ActivityData>

Remove an activity by ID.

Returns the removed activity data if it existed.

pub fn remove_many(&mut self, ids: &[String]) -> Vec<String>

Remove multiple activities.

Returns the IDs of activities that were actually removed.

pub fn clear(&mut self)

Clear all activities.

pub fn get(&self, id: &str) -> Option<&ActivityData>

Get an activity by ID.

pub fn get_coords(&self, id: &str) -> Option<&[GpsPoint]>

Get the coordinates for an activity.

pub fn get_sport_type(&self, id: &str) -> Option<&str>

Get the sport type for an activity.

pub fn contains(&self, id: &str) -> bool

Check if an activity exists.

pub fn ids(&self) -> impl Iterator<Item = &String>

Get all activity IDs.

pub fn iter(&self) -> impl Iterator<Item = (&String, &ActivityData)>

Get all activities.

pub fn values(&self) -> impl Iterator<Item = &ActivityData>

Get all activities as values.

pub fn len(&self) -> usize

Get the number of activities.

pub fn is_empty(&self) -> bool

Check if the store is empty.

pub fn sport_type_map(&self) -> HashMap<String, String>

Build a map of activity ID to sport type.

pub fn as_tracks(&self) -> Vec<(String, Vec<GpsPoint>)>

Build a vector of (id, coords) pairs for all activities.

pub fn compute_track_distance(coords: &[GpsPoint]) -> f64

Compute the total distance of a GPS track in meters.

Trait Implementations

impl Debug for ActivityStore

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

Formats the value using the given formatter.

impl Default for ActivityStore

fn default() -> ActivityStore

Returns the “default value” for a type.
