Struct Error 

pub struct Error {
    pub code: i32,
    pub message: String,
    pub data: Option<Value>,
}

JSON-RPC 2.0 error object

Fields

code: i32

message: String

data: Option<Value>

Implementations

impl Error

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

Create a new error

pub fn with_data(self, data: Value) -> Self

Add additional data to the error

pub fn is_parse_error(&self) -> bool

Check if this is a parse error (-32700)

pub fn is_invalid_request(&self) -> bool

Check if this is an invalid request error (-32600)

pub fn is_method_not_found(&self) -> bool

Check if this is a method not found error (-32601)

pub fn is_invalid_params(&self) -> bool

pub fn is_internal_error(&self) -> bool

pub fn is_server_error(&self) -> bool

pub fn code(&self) -> i32

pub fn message(&self) -> &str

pub fn data(&self) -> Option<&Value>

pub fn sanitized_with<F>(&self, transform: F) -> Self

where F: FnOnce(&Self) -> Self,

Transform this error using a custom callback function

This allows library users to implement their own error sanitization logic based on their security requirements.

Example

let sanitized = error.sanitized_with(|err| {
    if err.code() == INTERNAL_ERROR {
        Error::new(err.code(), "Internal server error")
    } else {
        err.clone()
    }
});

pub fn from_error_logged(error: &dyn Error) -> Self

Create a generic internal error from any std::error::Error

This logs the full error details server-side and returns a generic error. Use this with sanitized_with() for custom error transformation.

Trait Implementations

impl Clone for Error

fn clone(&self) -> Error

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Error

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Error

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for Error

fn eq(&self, other: &Error) -> 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 Error

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
