Struct mvt::GeomEncoder

pub struct GeomEncoder { /* fields omitted */ }

Encoder for Feature geometry.

This can consist of Point, Linestring or Polygon data.

Example

let geom_data = GeomEncoder::new(GeomType::Point, Transform64::default())
    .point(0.0, 0.0)
    .point(10.0, 0.0)
    .encode()?;

Implementations

impl GeomEncoder

pub fn new(geom_tp: GeomType, transform: Transform64) -> Self

Create a new geometry encoder.

• geom_tp Geometry type.
• transform Transform to apply to geometry.

pub fn add_point(&mut self, x: f64, y: f64)

Add a point.

pub fn point(self, x: f64, y: f64) -> Self

Add a point, taking ownership (for method chaining).

pub fn complete_geom(&mut self) -> Result<(), Error>

Complete the current geometry (for multilinestring / multipolygon).

pub fn complete(self) -> Result<Self, Error>

Complete the current geometry (for multilinestring / multipolygon).

pub fn encode(self) -> Result<GeomData, Error>

Encode the geometry data, consuming the encoder.
