Struct Error 

pub struct Error {
    pub code: ErrorCode,
    pub message: String,
    pub data: Option<Value>,
}

JSON-RPC Error Object.

Fields

code: ErrorCode

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

message: String

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

data: Option<Value>

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 fn new(code: ErrorCode) -> Self

Wraps given ErrorCode.

pub fn parse_error() -> Self

Creates a new ParseError error.

pub fn invalid_request() -> Self

Creates a new InvalidRequest error.

pub fn method_not_found() -> Self

Creates a new MethodNotFound error.

pub fn invalid_params<M>(message: M) -> Self

where M: Display,

Creates a new InvalidParams error with given message.

pub fn invalid_params_with_details<M, D>(message: M, details: D) -> Self

where M: Display, D: Display,

Creates a new InvalidParams error with given message and details.

pub fn internal_error() -> Self

Creates a new InternalError error.

pub fn invalid_version() -> Self

Creates a new InvalidRequest error with invalid version description.

Trait Implementations

impl Clone for Error

fn clone(&self) -> Error

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Error

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Error

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for Error

fn fmt(&self, f: &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 PartialEq for Error

fn eq(&self, other: &Error) -> 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 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.
