Struct RpcError 

pub struct RpcError {
    pub code: i32,
    pub message: String,
}

What a JSON-RPC response states in its error member.

Fields

code: i32

The code this failure carries.

message: String

The message this failure states.

Implementations

impl RpcError

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

Constructs a new RpcError.

impl RpcError

pub fn denoted<Failure>(failure: &Failure) -> Self

where Failure: RpcErrorAlg,

Reads the error a domain failure denotes.

pub fn parse_error() -> Self

States that a document is not JSON.

pub fn invalid_request() -> Self

States that a document is JSON but not a JSON-RPC request.

pub fn method_not_found(method: &str) -> Self

States that no method answers to a name.

Trait Implementations

impl Clone for RpcError

fn clone(&self) -> RpcError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RpcError

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

Formats the value using the given formatter.

impl Display for RpcError

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

Formats the value using the given formatter.

impl Eq for RpcError

impl Error for RpcError

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 PartialEq for RpcError

fn eq(&self, other: &RpcError) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.

impl RpcErrorAlg for RpcError

A domain can answer with this error directly, stating its own code and message.

fn rpc_code(&self) -> i32

The code the JSON-RPC specification carries for this failure.

fn rpc_message(&self) -> String

The message this failure states.

impl Serialize for RpcError

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
