Struct FfiChartStore 

pub struct FfiChartStore { /* private fields */ }

A chart, opened once and reused for as many route queries as the foreign side wants.

Wraps the store in a mutex for the same reason crate::FfiSimulator wraps its own state in one: a UniFFI object is handed to the foreign side as one shared reference, and ChartStore’s rusqlite::Connection is not Sync – nothing here mutates the chart, but more than one thread reaching into the same connection at once is still unsound.

Implementations

impl FfiChartStore

pub fn new(chart_path: String) -> Result<Self, FfiRouteError>

Opens a chart GeoPackage.

Errors

If the file cannot be opened, or is not a GeoPackage.

pub fn find_route( &self, from: FfiPosition, to: FfiPosition, safety_contour_m: f64, corridor_nm: f64, ) -> Result<Option<Vec<FfiPosition>>, FfiRouteError>

The shortest route between from and to this chart’s own safety check calls safe, for a vessel needing safety_contour_m of water and corridor_nm of cross-track room either side of the track – None if no such route exists within what route_find::find_route’s own auto-widening search settles for.

Errors

If the chart cannot be read.
