use typeway_server::Json;

#[derive(serde::Serialize)]
struct User { id: u32 }

async fn get_user() -> Result<Json<User>, JsonError> {
    // Return a structured JSON error on failure:
    Err(JsonError::not_found("user not found"))
}

Fields

Trait Implementations

impl Clone for JsonError

fn clone(&self) -> JsonError

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for JsonError

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for JsonError

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Error for JsonError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

impl From<(StatusCode, String)> for JsonError

Implement From<(StatusCode, String)> so existing extractor errors can be converted to JsonError automatically.

fn from((status, message): (StatusCode, String)) -> Self

Converts to this type from the input type.

impl IntoResponse for JsonError

fn into_response(self) -> Response<BoxBody>

Convert this value into an HTTP response.
