JsonRequest

modo::extractor

Struct JsonRequest

pub struct JsonRequest<T>(pub T);

Expand description

Axum extractor that deserializes a JSON request body into T and then sanitizes it.

Returns a 400 Bad Request error if the body is not valid JSON or cannot be deserialized. T must implement both serde::de::DeserializeOwned and crate::sanitize::Sanitize.

§Example

use modo::extractor::JsonRequest;
use modo::sanitize::Sanitize;
use serde::Deserialize;

#[derive(Deserialize)]
struct CreateItem { name: String }

impl Sanitize for CreateItem {
    fn sanitize(&mut self) { self.name = self.name.trim().to_string(); }
}

async fn create(JsonRequest(body): JsonRequest<CreateItem>) {
    // body.name is already trimmed
}

Trait Implementations§

impl<S, T> FromRequest<S> for JsonRequest<T>
where S: Send + Sync, T: DeserializeOwned + Sanitize,

type Rejection = Error

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

async fn from_request( req: Request<Body>, state: &S, ) -> Result<Self, Self::Rejection>

Perform the extraction.
