<p>The request writer has to write NSData objects into the provided Writeable. </p>
<p>The server will receive each of those separately and in order as distinct messages. A gRPC call might not complete until the request writer finishes. On the other hand, the request finishing doesn't necessarily make the call to finish, as the server might continue sending messages to the response side of the call indefinitely (depending on the semantics of the specific remote method called). To finish a call right away, invoke cancel. host parameter should not contain the scheme (<a href="http://">http://</a> or <a href="https://">https://</a>), only the name or IP addr and the port number, for example "localhost:5050". </p>

<p>The container of the request headers of an RPC conforms to this protocol, which is a subset of NSMutableDictionary's interface. </p>
<p>It will become a NSMutableDictionary later on. The keys of this container are the header names, which per the HTTP standard are case- insensitive. They are stored in lowercase (which is how HTTP/2 mandates them on the wire), and can only consist of ASCII characters. A header value is a NSString object (with only ASCII characters), unless the header name has the suffix "-bin", in which case the value has to be a NSData object. These HTTP headers will be passed to the server as part of this call. Each HTTP header is a name-value pair with string names and either string or binary values.</p>
<p>The passed dictionary has to use NSString keys, corresponding to the header names. The value associated to each can be a NSString object or a NSData object. E.g.:</p>
<p>call.requestHeaders ="authorization": @"Bearer ..."};</p>
<p>call.requestHeaders["my-header-bin"] = someData;</p>
<p>After the call is started, trying to modify this property is an error.</p>
<p>The property is initialized to an empty NSMutableDictionary. </p>
