Struct axum_msgpack::MsgPackRaw

pub struct MsgPackRaw<T>(pub T);

MessagePack Extractor / Response.

When used as an extractor, it can deserialize request bodies into some type that implements serde::Deserialize. If the request body cannot be parsed, or value of the Content-Type header does not match any of the application/msgpack, application/x-msgpack or application/*+msgpack it will reject the request and return a 400 Bad Request response.

Extractor example

use axum::{
    routing::post,
    Router,
};
use axum_msgpack::MsgPackRaw;
use serde::Deserialize;

#[derive(Deserialize)]
struct CreateUser {
    email: String,
    password: String,
}

async fn create_user(MsgPackRaw(payload): MsgPackRaw<CreateUser>) {
    // payload is a `CreateUser`
}

let app = Router::new().route("/users", post(create_user));

When used as a response, it can serialize any type that implements serde::Serialize to MsgPackRaw, and will automatically set Content-Type: application/msgpack header.

Response example

use axum::{
    extract::Path,
    routing::get,
    Router,
};
use axum_msgpack::MsgPackRaw;
use serde::Serialize;
use uuid::Uuid;

#[derive(Serialize)]
struct User {
    id: Uuid,
    username: String,
}

async fn get_user(Path(user_id) : Path<Uuid>) -> MsgPackRaw<User> {
    let user = find_user(user_id).await;
    MsgPackRaw(user)
}

async fn find_user(user_id: Uuid) -> User {
    // ...
}

let app = Router::new().route("/users/:id", get(get_user));

Trait Implementations

impl<T: Clone> Clone for MsgPackRaw<T>

fn clone(&self) -> MsgPackRaw<T>

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<T: Debug> Debug for MsgPackRaw<T>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<T: Default> Default for MsgPackRaw<T>

fn default() -> MsgPackRaw<T>

Returns the “default value” for a type.

impl<T> Deref for MsgPackRaw<T>

type Target = T

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

Dereferences the value.

impl<T> DerefMut for MsgPackRaw<T>

fn deref_mut(&mut self) -> &mut Self::Target

Mutably dereferences the value.

impl<T> From<T> for MsgPackRaw<T>

fn from(inner: T) -> Self

Converts to this type from the input type.

impl<T, S, B> FromRequest<S, B, ViaRequest> for MsgPackRaw<T>where
    T: DeserializeOwned,
    B: HttpBody + Send + 'static,
    B::Data: Send,
    B::Error: Into<BoxError>,
    S: Send + Sync,

type Rejection = MsgPackRejection

If the extractor fails it’ll use this “rejection” type. A rejection is a kind of error that can be converted into a response.

fn from_request<'life0, 'async_trait>(
    req: Request<B>,
    state: &'life0 S
) -> Pin<Box<dyn Future<Output = Result<Self, Self::Rejection>> + Send + 'async_trait>>where
    'life0: 'async_trait,
    Self: 'async_trait,

Perform the extraction.

impl<T> IntoResponse for MsgPackRaw<T>where
    T: Serialize,

fn into_response(self) -> Response

Create a response.

impl<T: Copy> Copy for MsgPackRaw<T>
