Implementations§

Source §

impl JsonrpcErrorError

Source

pub fn new( error_code: RpcErrorCodes, message: String, data: Option<Value>, ) -> Self

Constructs a new JsonrpcErrorError with the provided arguments.

§Arguments

error_code - The JSON-RPC error code.
message - A descriptive error message.
data - Optional additional data.

§Example

use serde_json::json;
use rust_mcp_schema::{JsonrpcErrorError, schema_utils::RpcErrorCodes};

let error = JsonrpcErrorError::new(RpcErrorCodes::INVALID_PARAMS, "Invalid params!".to_string(), Some(json!({"details": "Missing method field"})));
assert_eq!(error.code, -32602);
assert_eq!(error.message, "Invalid params!".to_string());

Source

pub fn method_not_found() -> Self

Creates a new JsonrpcErrorError for “Method not found”.

§Example

use rust_mcp_schema::JsonrpcErrorError;

let error = JsonrpcErrorError::method_not_found();
assert_eq!(error.code, -32601);
assert_eq!(error.message, "Method not found");

Source

pub fn invalid_params() -> Self

Creates a new JsonrpcErrorError for “Invalid parameters”.

§Example

use rust_mcp_schema::JsonrpcErrorError;

let error = JsonrpcErrorError::invalid_params();
assert_eq!(error.code, -32602);

Source

pub fn invalid_request() -> Self

Creates a new JsonrpcErrorError for “Invalid request”.

§Example

use rust_mcp_schema::JsonrpcErrorError;

let error = JsonrpcErrorError::invalid_request();
assert_eq!(error.code, -32600);

Source

pub fn internal_error() -> Self

Creates a new JsonrpcErrorError for “Internal error”.

§Example

use rust_mcp_schema::JsonrpcErrorError;

let error = JsonrpcErrorError::internal_error();
assert_eq!(error.code, -32603);

Source

pub fn parse_error() -> Self

Creates a new JsonrpcErrorError for “Parse error”.

§Example

use rust_mcp_schema::JsonrpcErrorError;

let error = JsonrpcErrorError::parse_error();
assert_eq!(error.code, -32700);

Source

pub fn with_message(self, message: String) -> Self

Sets a custom error message.

§Example

use rust_mcp_schema::JsonrpcErrorError;

let error = JsonrpcErrorError::invalid_request().with_message("Request format is invalid".to_string());
assert_eq!(error.message, "Request format is invalid".to_string());

Source

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

Attaches optional data to the error.

§Example

use serde_json::json;
use rust_mcp_schema::JsonrpcErrorError;

let error = JsonrpcErrorError::invalid_request().with_data(Some(json!({"reason": "Missing ID"})));
assert!(error.data.is_some());
