Struct cataclysm::http::Json

pub struct Json<J>(pub J);

Json extractor

Allows to use a structure that implements DeserializeOwned to extract information as json from the body of a request

use cataclysm::http::{Response, Json};
use serde::{Deserialize};

#[derive(Deserialize, Debug)]
struct BodyParams {
    name: String,
    last_name: Option<String>
}
 
async fn check_body(json: Json<BodyParams>) -> Response {
    log::info!("Http call containing {:?}", json.into_inner());
    Response::ok()
}

Deserialization error will result always in a bad request response

impl<J> Json<J>

pub fn into_inner(self) -> J

Retrieves the inner instance of the generic type

Trait Implementations

impl<J> Deref for Json<J>

type Target = J

The resulting type after dereferencing.

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

Dereferences the value.

impl<J> DerefMut for Json<J>

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

Mutably dereferences the value.

impl<T: Sync, J: 'static + DeserializeOwned + Send + Sync> Extractor<T> for Json<J>

fn extract(
    req: &Request,
    _additional: Arc<Additional<T>>
) -> Result<Self, Error>

Extract function, constructs Self from the request
