Struct ErrorData

pub struct ErrorData {
    pub code: ErrorCode,
    pub message: Cow<'static, str>,
    pub data: Option<Value>,
}

Error information for JSON-RPC error responses.

This structure follows the JSON-RPC 2.0 specification for error reporting, providing a standardized way to communicate errors between clients and servers.

Fields

code: ErrorCode

The error type that occurred (using standard JSON-RPC error codes)

message: Cow<'static, str>

A short description of the error. The message SHOULD be limited to a concise single sentence.

data: Option<Value>

Additional information about the error. The value of this member is defined by the sender (e.g. detailed error information, nested errors etc.).

Implementations

impl ErrorData

pub fn new( code: ErrorCode, message: impl Into<Cow<'static, str>>, data: Option<Value>, ) -> Self

pub fn resource_not_found( message: impl Into<Cow<'static, str>>, data: Option<Value>, ) -> Self

pub fn parse_error( message: impl Into<Cow<'static, str>>, data: Option<Value>, ) -> Self

pub fn invalid_request( message: impl Into<Cow<'static, str>>, data: Option<Value>, ) -> Self

pub fn method_not_found<M: ConstString>() -> Self

pub fn invalid_params( message: impl Into<Cow<'static, str>>, data: Option<Value>, ) -> Self

pub fn internal_error( message: impl Into<Cow<'static, str>>, data: Option<Value>, ) -> Self

Trait Implementations

impl Clone for ErrorData

fn clone(&self) -> ErrorData

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ErrorData

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ErrorData

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for ErrorData

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

Formats the value using the given formatter.

impl Error for ErrorData

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 JsonSchema for ErrorData

fn schema_name() -> Cow<'static, str>

The name of the generated JSON Schema.

fn schema_id() -> Cow<'static, str>

Returns a string that uniquely identifies the schema produced by this type.

fn json_schema(generator: &mut SchemaGenerator) -> Schema

Generates a JSON Schema for this type.

fn inline_schema() -> bool

Whether JSON Schemas generated for this type should be included directly in parent schemas, rather than being re-used where possible using the $ref keyword.

impl PartialEq for ErrorData

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for ErrorData

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
