Struct McpErrorResponse 

pub struct McpErrorResponse {
    pub error: McpError,
}

MCP error response (top-level)

Fields

error: McpError

Implementations

impl McpErrorResponse

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

pub fn canonical(code: McpErrorCode) -> Self

Construct with the spec-recommended canonical message for a given code.

Messages match error_schema.md “Recommended canonical messages” exactly.

Trait Implementations

impl Clone for McpErrorResponse

fn clone(&self) -> McpErrorResponse

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for McpErrorResponse

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for McpErrorResponse

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl From<McpErrorResponse> for JsonRpcError

Convert an MCP domain error into a JSON-RPC error.

The JSON-RPC code is derived from the MCP error code. The JSON-RPC message is the human-readable MCP message. The full MCP error object is carried in data for structured clients.

fn from(mcp: McpErrorResponse) -> Self

Converts to this type from the input type.

impl From<McpErrorResponse> for ToolResult

Convert an MCP domain error into a tool result with isError: true.

The text content is the JSON-serialized McpErrorResponse, preserving the structured error for clients that inspect tool output.

fn from(mcp: McpErrorResponse) -> Self

Converts to this type from the input type.

impl PartialEq for McpErrorResponse

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
