Struct ProblemRejection 

pub struct ProblemRejection {
    pub problem: Problem,
    pub format: ProblemFormat,
}

The rejection produced by ProblemJson and ProblemValidatedJson: an RFC 9457 Problem plus the ProblemFormat negotiated from the request’s Accept headers.

IntoResponse delegates to Problem::into_response_with, so the response carries the negotiated Content-Type with the problem body. Both fields are public, making the rejection inspectable in tests and reusable as the rejection type of custom extractors.

Requires the problem feature plus at least one of extract or validator.

Example

use axum::{http::{header, StatusCode}, response::IntoResponse};
use axum_api_kit::{Problem, ProblemFormat, ProblemRejection};

let rejection = ProblemRejection {
    problem: Problem::new(StatusCode::UNPROCESSABLE_ENTITY, "Unprocessable Entity")
        .with_detail("validation failed"),
    format: ProblemFormat::ProblemJson,
};
let res = rejection.into_response();
assert_eq!(res.status(), StatusCode::UNPROCESSABLE_ENTITY);
assert_eq!(
    res.headers().get(header::CONTENT_TYPE).unwrap(),
    "application/problem+json"
);

Fields

problem: Problem

The RFC 9457 problem details body (status, title, detail, and the code / details extension members carried over from the flat rejection mapping).

format: ProblemFormat

The response format negotiated from the request’s Accept headers.
