## Chunked transfer encoding
Actix automatically decode *chunked* encoding. `HttpRequest::payload()` already contains
decoded bytes stream. If request payload compressed with one of supported
compression codecs (br, gzip, deflate) bytes stream get decompressed.
Chunked encoding on response could be enabled with `HttpResponseBuilder::chunked()` method.
But this takes effect only for `Body::Streaming(BodyStream)` or `Body::StreamingContext` bodies.
Also if response payload compression is enabled and streaming body is used, chunked encoding
get enabled automatically.
Enabling chunked encoding for *HTTP/2.0* responses is forbidden.
```rust
# extern crate actix_web;
use actix_web::*;
use actix_web::headers::ContentEncoding;
fn index(req: HttpRequest) -> HttpResponse {
HttpResponse::Ok()
.chunked()
.body(Body::Streaming(Payload::empty().stream())).unwrap()
}
# fn main() {}
