Struct GpkgFeature 

pub struct GpkgFeature { /* private fields */ }

A single feature with geometry bytes and owned properties.

Implementations

impl GpkgFeature

pub fn id(&self) -> i64

Return the primary key value.

Example:

use rusqlite_gpkg::Gpkg;

let gpkg = Gpkg::open_read_only("data/example.gpkg")?;
let layer = gpkg.get_layer("points")?;
let features = layer.features()?;
let feature = features.first().expect("feature");
let _id = feature.id();

pub fn geometry(&self) -> Result<Wkb<'_>>

Decode the geometry column into WKB.

Example:

use rusqlite_gpkg::Gpkg;

let gpkg = Gpkg::open_read_only("data/example.gpkg")?;
let layer = gpkg.get_layer("points")?;
let features = layer.features()?;
let feature = features.first().expect("feature");
let _geom = feature.geometry()?;

pub fn property(&self, name: &str) -> Option<Value>

Read a property by name as an owned Value.

Example:

use rusqlite_gpkg::Gpkg;

let gpkg = Gpkg::open_read_only("data/example.gpkg")?;
let layer = gpkg.get_layer("points")?;
let features = layer.features()?;
let feature = features.first().expect("feature");
let value: String = feature
    .property("name")
    .ok_or("missing name")?
    .try_into()?;

pub fn properties(&self) -> &[Value]

Return the ordered property values as stored in the feature.
