Transport-specific errors for different MCP transport mechanisms.

Each transport type (stdio, HTTP+SSE, HTTP streaming) can have specific failure modes that need to be handled appropriately.

Implementations

impl TransportError

pub fn is_retryable(&self) -> bool

Check if this transport error is retryable.

Trait Implementations

impl Clone for TransportError

fn clone(&self) -> TransportError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TransportError

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

Formats the value using the given formatter.

impl Display for TransportError

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

Formats the value using the given formatter.

impl Error for TransportError

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<TransportError> for McpError

fn from(source: TransportError) -> Self

Converts to this type from the input type.
