Module api_errors 

Standardized API error responses. See api_errors::ApiError. Standardized API error responses.

All errors share a consistent JSON shape so frontends can parse them uniformly. Follows the RFC 7807 “Problem Details” convention loosely:

{
  "error":   "validation_failed",
  "message": "title cannot be empty",
  "status":  422,
  "details": {"field": "title"}
}

Quick start

use rustango::api_errors::ApiError;

async fn create_post(body: Json<NewPost>) -> Result<Json<Post>, ApiError> {
    if body.title.is_empty() {
        return Err(ApiError::validation("title cannot be empty")
            .with_field("title"));
    }
    // ...
}

ApiError implements axum::response::IntoResponse, so any handler returning Result<T, ApiError> produces a properly-shaped error response.
