Enumeration of errors.

Variants

Parse

Fields

data: String

The underlying JSON error message.

Error generated when a JSON payload cannot be parsed.

InvalidRequest

Fields

data: String

The underlying JSON error message.

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

MethodNotFound

Fields

id: Option<Value>

The id of the request message.

name: String

The name of the request method.

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

InvalidParams

Fields

id: Option<Value>

The id of the request message.

data: String

The underlying JSON error message.

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

Boxed(Box<dyn Error + Send + Sync>)

Generic error type converted to an internal error response.

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.

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

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

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

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
