Enum ErrorCode

#[repr(i32)]
pub enum ErrorCode {
    ParseError = -32_700,
    InvalidRequest = -32_600,
    MethodNotFound = -32_601,
    InvalidParams = -32_602,
    InternalError = -32_603,
    ServerNotInitialized = -32_002,
    UnknownErrorCode = -32_001,
    RequestFailed = -32_000,
}

Error codes as defined in the MCP protocol.

These error codes are based on the JSON-RPC 2.0 specification with additional MCP-specific error codes in the -32000 to -32099 range.

Variants

ParseError = -32_700

Invalid JSON was received by the server. An error occurred on the server while parsing the JSON text.

InvalidRequest = -32_600

The JSON sent is not a valid Request object.

MethodNotFound = -32_601

The method does not exist / is not available.

InvalidParams = -32_602

Invalid method parameter(s).

InternalError = -32_603

Internal JSON-RPC error.

ServerNotInitialized = -32_002

Server has not been initialized. This error is returned when a request is made before the server has been properly initialized.

UnknownErrorCode = -32_001

Unknown error code. This error is returned when an error code is received that is not recognized by the implementation.

RequestFailed = -32_000

Request failed. This error is returned when a request fails for a reason not covered by other error codes.

Trait Implementations

impl Clone for ErrorCode

fn clone(&self) -> ErrorCode

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ErrorCode

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

Formats the value using the given formatter.

impl Display for ErrorCode

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

Formats the value using the given formatter.

impl From<ErrorCode> for i32

fn from(code: ErrorCode) -> Self

Converts to this type from the input type.

impl From<i32> for ErrorCode

fn from(code: i32) -> Self

Converts to this type from the input type.

impl PartialEq for ErrorCode

fn eq(&self, other: &ErrorCode) -> 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.
