PayloadTooLarge

Request body exceeds the size limit.

Fields

size: usize

The actual body size.

limit: usize

The configured limit.

DeserializeError

JSON deserialization failed.

Fields

message: String

Trait Implementations

impl Debug for JsonExtractError

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

Formats the value using the given formatter.

impl Display for JsonExtractError

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

Formats the value using the given formatter.

impl Error for JsonExtractError

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 IntoResponse for JsonExtractError

fn into_response(self) -> Response

Convert into a response.
