Enum Error

pub enum Error {
    SerializeJSON(Error),
    DeserializeURLEncoded(Error),
    Payload(PayloadError),
    NotFound,
    MethodNotAllowed,
    NoPayload,
}

Variants

SerializeJSON(Error)

an error occurred when trying to serialize from a json body payload

DeserializeURLEncoded(Error)

an error occurred when trying to deserialize from a url encoded query string

Payload(PayloadError)

an error occurred when trying to deserialize from the request body

NotFound

the route did not match what was expected this variant will never bubble, because it’s “caught” by the default_router which if not provided will cause a compiler_error from the router macro

MethodNotAllowed

the method did not match what was expected

NoPayload

there was no payload sent bt all handlers are expected to get data, if you want to get no data, use the “unit” type of that data format, i.e in json this is null or use an empty struct

Implementations

impl Error

pub fn is_not_found(&self) -> bool

checks if not found 404

pub fn status_code(&self) -> u16

convert errors to status codes

pub fn json(&self) -> Result<String, Self>

wraps the error in a Result<(), Error> and serializes as json

Trait Implementations

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

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<Error> for Error

fn from(source: Error) -> Self

Converts to this type from the input type.

impl From<Error> for Error

fn from(source: Error) -> Self

Converts to this type from the input type.

impl Serialize for Error

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
