# dot\_json [![Build Status](https://travis-ci.org/prewk/dot_json.svg?branch=master)](https://travis-ci.org/prewk/dot_json)

Utilities for working with `serde_json::Map` structures as "dot maps".

```
[dependencies]
dot_json = "0.2"

```rust
#[macro_use]
extern crate serde_json;

use dot_json::value_to_dot;
use serde_json::{Map, Value};

fn main() {
	let obj = json!({

		}
	});
		
	let obj_dot = value_to_dot(&obj);
	
	// obj_dot is now: {
	//     "foo": "Lorem ipsum",
	//     "bar.0": 123,
	//     "bar.1": null,
	//     "bar.2.baz": "Dolor sit amet",

## map\_to\_dot\_map

Used by `value_to_dot` and `arr_to_dot_map` to convert deep `serde_json::Map` to shallow dot maps.

## arr\_to\_dot\_map

Used by `value_to_dot` to convert deep `serde_json::Value::Array` vectors to shallow dot maps.
