Implementations

impl McpError

pub fn severity(&self) -> ErrorSeverity

Get the severity level of this error

pub fn recovery_strategy(&self) -> RecoveryStrategy

Get the recovery strategy for this error

pub fn should_retry(&self) -> bool

Check if this error should trigger a retry

pub fn json_rpc_code(&self) -> i32

Get JSON-RPC error code

pub fn error_type_name(&self) -> &'static str

Get error type name as string for serialization

pub fn to_json_rpc_error(&self) -> JsonRpcError

Convert to JSON-RPC error

Trait Implementations

impl Clone for McpError

fn clone(&self) -> McpError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for McpError

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

Formats the value using the given formatter.

impl Display for McpError

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

Formats the value using the given formatter.

impl Error for McpError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0: use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0: replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

impl From<Error> for McpError

fn from(source: CoreError) -> Self

Converts to this type from the input type.
