Enum Error 

pub enum Error {
    ProtocolError(String),
    RpcError {
        code: i32,
        message: String,
    },
    ParseError(Error),
    InvalidRequest(String),
}

Internal errors that can occur during JSON-RPC processing.

These are implementation-level errors, separate from the JSON-RPC protocol error objects that are sent over the wire (defined in types::Error).

Variants

ProtocolError(String)

Protocol-level error, such as invalid method or parameters.

RpcError

JSON-RPC error with specific code and message.

Fields

code: i32

message: String

ParseError(Error)

JSON parsing error.

InvalidRequest(String)

Invalid JSON-RPC request error.

Implementations

impl Error

pub fn protocol(message: impl Into<String>) -> Self

Create a new protocol error.

pub fn rpc(code: i32, message: impl Into<String>) -> Self

Create a new JSON-RPC error with a specific code and message.

pub fn invalid_request(message: impl Into<String>) -> Self

Create a new Invalid Request error.

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)>

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 From<Error> for Error

fn from(source: Error) -> Self

Converts to this type from the input type.
