Enum ErrorCode

pub enum ErrorCode {
    ParseError,
    InvalidRequest,
    MethodNotFound,
    InvalidParams,
    InternalError,
    ServerError(i64),
}

Standard JSON-RPC 2.0 error codes

This enum represents the predefined error codes as specified in the JSON-RPC 2.0 specification, along with support for custom server error codes.

Variants

ParseError

Invalid JSON was received by the server. An error occurred on the server while parsing the JSON text. Error code: -32700

InvalidRequest

The JSON sent is not a valid Request object. Error code: -32600

MethodNotFound

The method does not exist / is not available. Error code: -32601

InvalidParams

Invalid method parameter(s). Error code: -32602

InternalError

Internal JSON-RPC error. Error code: -32603

ServerError(i64)

Reserved for implementation-defined server-errors. Error codes from -32000 to -32099 are reserved for implementation-defined server-errors. The i64 value represents the custom error code.

Implementations

impl ErrorCode

pub fn code(&self) -> i64

Returns the numeric error code as defined in the JSON-RPC 2.0 specification

Returns

The corresponding error code number:

• ParseError: -32700
• InvalidRequest: -32600
• MethodNotFound: -32601
• InvalidParams: -32602
• InternalError: -32603
• ServerError: the custom code provided

pub fn as_str(&self) -> &'static str

Returns a human-readable description of the error

Returns

A static string slice containing the error description

Trait Implementations

impl Clone for ErrorCode

fn clone(&self) -> ErrorCode

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ErrorCode

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

Formats the value using the given formatter.

impl Display for ErrorCode

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

Formats the error code as a string

Arguments

• f - The formatter to write the error code to

Returns

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

impl PartialEq for ErrorCode

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