# OSM Overpass

A library to query OSM Overpass servers

# Example
## Async example
```
let url = String::from("https://overpass-api.de/api/interpreter");
let query = "
[out:json][timeout:30];
node(3662847634);
// print results
out;
";
let api = api::OverpassAPI::new(url);
let res = api.query(String::from(query)).await;
...
```
## Sync example
```
...
let res = api.query_sync(String::from(query));
```

## Using query response
```
...
let unwrapped = res.unwrap();
//unwrapped is iterable, so
for nwr in unwrapped {
    match nwr {
        NWR::Node(n) => ...,
        NWR::Way(w) => ...,  
        NWR::Relation(r) => ...      
    }
}
```
# Notes
Queries must return a JSON result. Put `[out:json]` in the first line of
the query to do this.
