Struct Error

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

JSON-RPC 2.0 Error Object

Represents an error that occurred during the processing of a JSON-RPC request. This struct follows the JSON-RPC 2.0 specification for error objects.

Fields

• code - A number that indicates the error type that occurred
• message - A string providing a short description of the error
• data - Optional additional information about the error

Fields

code: i64

The error code number

message: String

A short description of the error

data: Option<Value>

Optional additional error data

Implementations

impl Error

pub fn new(code: ErrorCode) -> Self

Creates a new Error from an ErrorCode

Arguments

• code - The error code to create the error from

Returns

A new Error instance with the appropriate code and message

Examples

use jsonrpc_lite::error::{Error, ErrorCode};

let error = Error::new(ErrorCode::MethodNotFound);
assert_eq!(error.code, -32601);
assert_eq!(error.message, "Method not found");

pub fn parse_error() -> Self

Creates a parse error (-32700)

Returns

A new Error instance representing a parse error

pub fn invalid_request() -> Self

Creates an invalid request error (-32600)

Returns

A new Error instance representing an invalid request error

pub fn method_not_found() -> Self

Creates a method not found error (-32601)

Returns

A new Error instance representing a method not found error

pub fn invalid_params() -> Self

Creates an invalid params error (-32602)

Returns

A new Error instance representing an invalid params error

pub fn internal_error() -> Self

Creates an internal error (-32603)

Returns

A new Error instance representing an internal error

Trait Implementations

impl Clone for Error

fn clone(&self) -> Error

Returns a duplicate of the value.

const 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 error as a JSON string for display

Arguments

• f - The formatter to write to

Returns

A fmt::Result indicating success or failure of the formatting operation

impl Error for Error

fn description(&self) -> &str

👎Deprecated since 1.42.0: use the Display impl or to_string()

Returns a description of the error

Returns

A string slice containing the error message

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

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 #99301)

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 ==.

const 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.
