Struct JsonRpcError 

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

JSON-RPC 2.0 Error Object

When a RPC call encounters an error, the Response object MUST contain an error member with this structure.

Fields

code: ErrorCode

Error code indicating the type of error

message: String

Short description of the error

data: Option<Value>

Additional information about the error (optional)

Trait Implementations

impl Clone for JsonRpcError

fn clone(&self) -> JsonRpcError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for JsonRpcError

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for JsonRpcError

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for JsonRpcError

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

Formats the value using the given formatter.

impl Error for JsonRpcError

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 Serialize for JsonRpcError

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
