Implementations

impl JsonRpcError

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

Create a new JSON-RPC error with the given parameters

Examples

use prism_mcp_rs::protocol::JsonRpcError;
use serde_json::json;

let error = JsonRpcError::new(
    json!("req-123"),
    -32601,
    "Method not found"
);

pub fn with_data<S: Into<String>>( id: RequestId, code: i32, message: S, data: Option<Value>, ) -> Self

Create a new JSON-RPC error with additional data

Examples

use prism_mcp_rs::protocol::JsonRpcError;
use serde_json::json;

let error = JsonRpcError::with_data(
    json!("req-123"),
    -32602,
    "Invalid params",
    Some(json!({"expected": "string", "got": "number"}))
);

pub fn parse_error(id: RequestId) -> Self

Create a “Parse error” response (-32700)

Invalid JSON was received by the server

pub fn invalid_request(id: RequestId) -> Self

Create an “Invalid Request” response (-32600)

The JSON sent is not a valid Request object

pub fn method_not_found(id: RequestId) -> Self

Create a “Method not found” response (-32601)

The method does not exist or is not available

pub fn method_not_found_with_name<S: Into<String>>( id: RequestId, method: S, ) -> Self

Create a “Method not found” response with the method name

pub fn invalid_params(id: RequestId) -> Self

Create an “Invalid params” response (-32602)

Invalid method parameter(s)

pub fn invalid_params_with_message<S: Into<String>>( id: RequestId, details: S, ) -> Self

Create an “Invalid params” response with details

pub fn internal_error(id: RequestId) -> Self

Create an “Internal error” response (-32603)

Internal JSON-RPC error

pub fn internal_error_with_message<S: Into<String>>( id: RequestId, details: S, ) -> Self

Create an “Internal error” response with details

pub fn tool_not_found<S: Into<String>>(id: RequestId, tool_name: S) -> Self

Create a “Tool not found” error (-32000)

MCP-specific: The requested tool does not exist

pub fn resource_not_found<S: Into<String>>(id: RequestId, uri: S) -> Self

Create a “Resource not found” error (-32001)

MCP-specific: The requested resource does not exist

pub fn prompt_not_found<S: Into<String>>(id: RequestId, prompt_name: S) -> Self

Create a “Prompt not found” error (-32002)

MCP-specific: The requested prompt does not exist

pub fn custom<S: Into<String>>(id: RequestId, code: i32, message: S) -> Self

Create a custom error with a specific code and message

pub fn custom_with_data<S: Into<String>>( id: RequestId, code: i32, message: S, data: Value, ) -> Self

Create a custom error with a specific code, message, and data

impl JsonRpcError

pub fn error( id: RequestId, code: i32, message: String, data: Option<Value>, ) -> Self

Create an error JSON-RPC response

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 From<JsonRpcError> for JsonRpcMessage

fn from(error: JsonRpcError) -> Self

Converts to this type from the input type.

impl IntoJsonRpcMessage for JsonRpcError

fn into_message(self) -> JsonRpcMessage

impl PartialEq for JsonRpcError

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl StructuralPartialEq for JsonRpcError

impl TryFrom<JsonRpcMessage> for JsonRpcError

type Error = McpError

The type returned in the event of a conversion error.

fn try_from(msg: JsonRpcMessage) -> Result<Self, Self::Error>

Performs the conversion.
