Struct GeoLayer 

pub struct GeoLayer {
    pub space: CoordinateSpace,
    pub kind: Option<CoordsKind>,
    pub features: Vec<GeoFeature>,
}

A standalone geographic document: element points and routes in one coordinate space, keyed by element identity rather than embedded in a case.

Fields

space: CoordinateSpace

Coordinate space of every feature.

kind: Option<CoordsKind>

Default provenance, stamped into the powerio_geo member on write.

features: Vec<GeoFeature>

Implementations

impl GeoLayer

pub fn parse_bytes(bytes: &[u8], name_hint: Option<&str>) -> Result<GeoParsed>

Tolerant read of a geographic sidecar from bytes. name_hint (a file name) picks CSV against JSON when present; otherwise the content is sniffed. Accepts headerless buscoords CSV (bus,x,y), CSV and JSON records with aliased field names, and GeoJSON Point/LineString features. Rejects input carrying no usable coordinates.

pub fn extracted_geojson(&self) -> Result<String>

to_geojson behind the extraction surfaces’ shared guard: an empty layer is refused because the written document would not read back (parse_bytes rejects a document with no features).

pub fn to_geojson(&self) -> String

Serialize the canonical form: a GeoJSON FeatureCollection with the powerio_geo foreign member. Valid RFC 7946 GeoJSON when the space is geographic, so GIS tools open it directly.

Trait Implementations

impl Clone for GeoLayer

fn clone(&self) -> GeoLayer

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for GeoLayer

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

Formats the value using the given formatter.

impl PartialEq for GeoLayer

fn eq(&self, other: &GeoLayer) -> 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.
