Function to_json 

pub fn to_json<T: Writer, M: Clone + Serialize, P: Clone + Default + Serialize, D: Clone + Default + Serialize, I: FeatureReader<M, P, D>>(
    writer: &mut T,
    readers: Vec<&I>,
    opts: Option<ToJSONOptions<M, P, D>>,
)

To JSON

Description

Given a writer and an array of readers, write the input features to the writer as a JSON object

Parameters

• writer: the buffer or file to write to. See Writer for what writers are available
• readers: Any reader that implements the FeatureReader trait can be used
• opts: user defined options on how to write the features

Usage

use gistools::{readers::JSONReader, parsers::{BufferWriter, FileReader}, writers::{to_json, ToJSONOptions}};
use s2json::{MValueCompatible, Projection};
use serde::{Deserialize, Serialize};
use std::path::PathBuf;

#[derive(Debug, Default, Clone, MValueCompatible, PartialEq, Serialize, Deserialize)]
#[serde(default)]
struct Props {
    name: String,
}

let mut path = PathBuf::from(env!("CARGO_MANIFEST_DIR"));
path = path.join("tests/writers/fixtures/points.geojson");

let reader: JSONReader<FileReader, (), Props, ()> = JSONReader::new(FileReader::from(path));
let mut writer = BufferWriter::default();

// write
to_json(
    &mut writer,
    vec![&reader],
    Some(ToJSONOptions {
        projection: Some(Projection::WG),
        geojson: Some(true),
        ..Default::default()
    }),
);
