pub enum ServerError {
    JsonRpc(JsonRpcError),
    Transport(TransportError),
    Json(Error),
    Io(Error),
    Server {
        code: ErrorCode,
        message: String,
        source: Option<Box<dyn StdError + Send + Sync>>,
    },
}

Server-specific error type

Variants

JsonRpc(JsonRpcError)

JSON-RPC protocol error

Transport(TransportError)

Transport error

Json(Error)

JSON serialization/deserialization error

Io(Error)

I/O error

Server

Server error with code and message

Fields

code: ErrorCode

The error code

message: String

Error message

source: Option<Box<dyn StdError + Send + Sync>>

Optional error source

Implementations

impl ServerError

pub fn new(code: ErrorCode, message: impl Into<String>) -> Self

Create a new server error

pub fn with_source( code: ErrorCode, message: impl Into<String>, source: impl Into<Box<dyn StdError + Send + Sync>>, ) -> Self

Create a new server error with source

pub fn code(&self) -> Option<ErrorCode>

Get the error code if this is a server error

Trait Implementations

impl Debug for ServerError

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

Formats the value using the given formatter.

impl Display for ServerError

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

Format the error message

impl Error for ServerError

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

Get the error source

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.
