[][src]Struct rocket_contrib::msgpack::MsgPack

pub struct MsgPack<T>(pub T);

The MsgPack type: implements FromData and Responder, allowing you to easily consume and respond with MessagePack data.

Receiving MessagePack

If you're receiving MessagePack data, simply add a data parameter to your route arguments and ensure the type of the parameter is a MsgPack<T>, where T is some type you'd like to parse from MessagePack. T must implement Deserialize from serde. The data is parsed from the HTTP request body.

use rocket_contrib::msgpack::MsgPack;

#[post("/users", format = "msgpack", data = "<user>")]
fn new_user(user: MsgPack<User>) {
    /* ... */
}

You don't need to use format = "msgpack", but it may be what you want. Using format = msgpack means that any request that doesn't specify "application/msgpack" as its first Content-Type: header parameter will not be routed to this handler.

Sending MessagePack

If you're responding with MessagePack data, return a MsgPack<T> type, where T implements Serialize from serde. The content type of the response is set to application/msgpack automatically.

use rocket_contrib::msgpack::MsgPack;

#[get("/users/<id>")]
fn user(id: usize) -> MsgPack<User> {
    let user_from_id = User::from(id);
    /* ... */
    MsgPack(user_from_id)
}

Incoming Data Limits

The default size limit for incoming MessagePack data is 1MiB. Setting a limit protects your application from denial of service (DOS) attacks and from resource exhaustion through high memory consumption. The limit can be increased by setting the limits.msgpack configuration parameter. For instance, to increase the MessagePack limit to 5MiB for all environments, you may add the following to your Rocket.toml:

[global.limits]
msgpack = 5242880

Methods

impl<T> MsgPack<T>
[src]

Consumes the MsgPack wrapper and returns the wrapped item.

Example

let string = "Hello".to_string();
let my_msgpack = MsgPack(string);
assert_eq!(my_msgpack.into_inner(), "Hello".to_string());

impl<T: Serialize> Responder<'static> for MsgPack<T>
[src]
