elastic_responses 0.20.4

# [`elastic_responses`](https://docs.rs/elastic_responses/*/elastic_responses/) [![Latest Version](https://img.shields.io/crates/v/elastic_responses.svg)](https://crates.io/crates/elastic_responses)


A crate to handle parsing and handling Elasticsearch search results which provides convenient iterators to step through the results returned.

## Example

 
`Cargo.toml`
```
[dependencies]
elastic_reqwest = "*"
elastic_responses = "*" 
```

### Search


Query your Elasticsearch Cluster, then iterate through the results:

```rust
// Send a request (omitted, see `samples/basic`, and read the response.
let mut res = client.elastic_req(&params, SearchRequest::for_index("_all", body)).unwrap();

// Parse body to JSON
let response = parse::<SearchResponse<Value>>().from_reader(res.status().to_u16(), res).unwrap();

// Use hits() or aggs() iterators
// Hits
for hit in response.hits() {
    println!("{:?}", hit);
}

// Agregations
for agg in response.aggs() {
    println!("{:?}", agg);
}
```

### Bulk


Bulk response operations are split by whether they succeeded or failed:

```rust
// Send a request (omitted, see `samples/bulk`, and read the response.
let mut res = client.elastic_req(&params, BulkRequest::new(body)).unwrap();

// Parse body to JSON
let response = parse::<BulkResponse>().from_reader(res.status().to_u16(), res).unwrap();

for op in response.into_iter() {
    match op {
        Ok(ok) => {
            // Do something with successful operations
            println!("ok: {:?}", op);
        },
        Err(err) => {
            // Do something with failed operations
            println!("{:?}", op);
        }
    }
}
```
