Enumeration of errors.

Variants

Parse

Error generated when a JSON payload cannot be parsed.

Fields of Parse

data: String

The underlying JSON error message.

InvalidRequest

Error generated when the contents of a JSON payload do not match the request type semantics.

Fields of InvalidRequest

data: String

The underlying JSON error message.

MethodNotFound

Error generated when the request method name did not match any services.

Fields of MethodNotFound

id: Value

The id of the request message.

name: String

The name of the request method.

InvalidParams

Error generated when request parameters cannot be converted to the expected type.

Fields of InvalidParams

id: Value

The id of the request message.

data: String

The underlying JSON error message.

Boxed(Box<dyn Error + Send>)

Generic error type converted to an internal error response.

Implementations

impl Error

pub fn boxed(e: impl Error + Send + 'static) -> Self

Helper function to Box an error implementation.

Service handlers can call map_err(Error::boxed)? to propagate foreign errors.

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)>

The lower-level source of this error, if any.

pub fn backtrace(&self) -> Option<&Backtrace>

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

Returns a stack backtrace, if available, of where this error occurred.

pub fn description(&self) -> &str

👎 Deprecated since 1.42.0:

use the Display impl or to_string()

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

👎 Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

impl From<Box<dyn Error + 'static + Send, Global>> for Error

fn from(source: Box<dyn Error + Send>) -> Self

Performs the conversion.

impl<'a> Into<(isize, Option<String>)> for &'a Error

fn into(self) -> (isize, Option<String>)

Performs the conversion.

impl Into<Response> for Error

fn into(self) -> Response

Performs the conversion.
