Struct Error 

pub struct Error<T = Value> {
    pub code: i64,
    pub message: String,
    pub data: Option<T>,
}

A JSON-RPC 2.0 error object.

Fields

code: i64

A Number that indicates the error type that occurred. This MUST be an integer.

See the associated constants for error types defined by the specification.

message: String

A String providing a short description of the error. The message SHOULD be limited to a concise single sentence.

data: Option<T>

A Primitive or Structured value that contains additional information about the error. This may be omitted. The value of this member is defined by the Server (e.g. detailed error information, nested errors etc.).

Implementations

impl Error

pub const PARSE_ERROR: i64 = -32_700i64

Invalid JSON was received by the server. An error occurred on the server while parsing the JSON text.

pub const INVALID_REQUEST: i64 = -32_600i64

The JSON sent is not a valid Request object.

pub const METHOD_NOT_FOUND: i64 = -32_601i64

The method does not exist / is not available.

pub const INVALID_PARAMS: i64 = -32_602i64

Invalid method parameter(s).

pub const INTERNAL_ERROR: i64 = -32_603i64

Internal JSON-RPC error.

impl<T> Error<T>

pub fn parse_error( message: impl Display, data: impl Into<Option<T>>, ) -> Error<T>

Convenience method for creating a new error with code Self::PARSE_ERROR

pub fn invalid_request( message: impl Display, data: impl Into<Option<T>>, ) -> Error<T>

Convenience method for creating a new error with code Self::INVALID_REQUEST

pub fn method_not_found( message: impl Display, data: impl Into<Option<T>>, ) -> Error<T>

Convenience method for creating a new error with code Self::METHOD_NOT_FOUND

pub fn invalid_params( message: impl Display, data: impl Into<Option<T>>, ) -> Error<T>

Convenience method for creating a new error with code Self::INVALID_PARAMS

pub fn internal_error( message: impl Display, data: impl Into<Option<T>>, ) -> Error<T>

Convenience method for creating a new error with code Self::INTERNAL_ERROR

pub const fn spec_message(&self) -> Option<&'static str>

If Self::code is one of the predefined errors in the spec, get its associated error message.

impl Error

pub const SERVER_ERROR_RANGE: RangeInclusive<i64>

Reserved for implementation-defined server-errors.

impl<T> Error<T>

pub fn new( code: i64, message: impl Display, data: impl Into<Option<T>>, ) -> Error<T>

Convenience method for creating a new error.

Trait Implementations

impl<T> Clone for Error<T>

where T: Clone,

fn clone(&self) -> Error<T>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<T> Debug for Error<T>

where T: Debug,

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

Formats the value using the given formatter.

impl<T> Default for Error<T>

where T: Default,

fn default() -> Error<T>

Returns the “default value” for a type.

impl<'de, T> Deserialize<'de> for Error<T>

where T: Deserialize<'de>,

fn deserialize<__D>( __deserializer: __D, ) -> Result<Error<T>, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl<T> Display for Error<T>

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

Formats the value using the given formatter.

impl<T> Error for Error<T>

where T: Debug,

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<T> PartialEq for Error<T>

where T: PartialEq,

fn eq(&self, other: &Error<T>) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl<T> Serialize for Error<T>

where T: Serialize,

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl<T> Eq for Error<T>

where T: Eq,
