Method content_length

src/http/body.rs:192–198

Get a value for the length of this `Body`'s content, in bytes, if known. This value can come from either the Content-Length header received in the incoming request or response assocated with the body, or be provided by an exact `http_body::Body::size_hint` if the `Body` is constructed from an `http_body::Body` impl.
