Struct RpcError 

pub struct RpcError {
    pub code: ErrorCode,
    pub message: String,
    pub data: ErrorData,
}

The canonical DIG-node RPC error object: {code, message, data:{code, origin}}.

Build one with RpcError::new (or the code-specific helpers) so the numeric code, the data.code machine string, and the origin can never drift apart.

Fields

code: ErrorCode

The numeric wire code.

message: String

A human-readable message. May be refined over time; data.code is the stable branch key.

data: ErrorData

Structured, machine-branchable context.

Implementations

impl RpcError

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

The single constructor: mint the canonical envelope from a code, a message, and an origin. data.code is derived from code so the two can never disagree.

pub fn of(code: ErrorCode, message: impl Into<String>) -> RpcError

Mint an error using the code’s default origin.

pub fn code_only(code: ErrorCode) -> RpcError

Mint an error using both the code’s default origin and its default message.

pub fn with_redirect(self, redirect: RedirectInfo) -> RpcError

Attach a RedirectInfo payload (for ContentRedirect).

pub fn with_extra(self, key: impl Into<String>, value: Value) -> RpcError

Attach one extra data field (flattened onto data).

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<(), Error>

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for RpcError

fn deserialize<__D>( __deserializer: __D, ) -> Result<RpcError, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for RpcError

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

Formats the value using the given formatter.

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 Serialize for RpcError

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
