Struct geobuf::encode::Encoder

pub struct Encoder { /* fields omitted */ }

GeoJSON to Geobuf encoder

Implementations

impl Encoder

pub fn encode(
    geojson: &JSONValue,
    precision: u32,
    dim: u32
) -> Result<Data, &'static str>

Returns a Geobuf encoded object from the given geojson value

Arguments

• geojson - A serde_json::Value that contains a valid geojson object.
• precision - max number of digits after the decimal point in coordinates.
• dim - number of dimensions in coordinates.

Example

use geobuf::encode::Encoder;
use geobuf::geobuf_pb::Data_Geometry_Type;
use serde_json;

let geojson = serde_json::from_str(r#"{"type": "Point", "coordinates": [100.0, 0.0]}"#).unwrap();
let geobuf = Encoder::encode(&geojson, 6, 2).unwrap();
assert_eq!(geobuf.get_dimensions(), 2);
assert_eq!(geobuf.get_precision(), 6);
assert_eq!(geobuf.get_geometry().get_field_type(), Data_Geometry_Type::POINT);
