axum-yaml

axum-yaml adds YAML features to axum

Features

Serialize, Deserialize YAML from request/response

Usage Example

Extractor example

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 it does not contain the Content-Type: application/yaml header, it will reject the request and return a 400 Bad Request response.

use axum::{
    extract,
    routing::post,
    Router,
};
use axum_yaml::Yaml;
use serde::Deserialize;

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

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

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

[!NOTE] Also, you can construct a Yaml<T> from a byte slice (Yaml::from_bytes()). Most users should prefer to use the FromRequest impl but special cases may require first extracting a Request into Bytes then optionally constructing a Yaml<T>.

Response example

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

use axum::{
    extract::Path,
    routing::get,
    Router,
};

use axum_yaml::Yaml;
use serde::Serialize;
use uuid::Uuid;

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

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

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

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