Represents errors that can occur during transport operations.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

ConnectionFailed(String)

Failed to establish a connection.

ConnectionLost(String)

An established connection was lost.

SendFailed(String)

Failed to send a message.

ReceiveFailed(String)

Failed to receive a message.

SerializationFailed(String)

Failed to serialize or deserialize a message.

ProtocolError(String)

A protocol-level error occurred.

Timeout

The operation did not complete within the specified timeout.

ConnectionTimeout

Connection establishment timed out.

Fields

operation: String

The operation that timed out

timeout: Duration

The timeout duration that was exceeded

RequestTimeout

Single request timed out.

Fields

operation: String

The operation that timed out

timeout: Duration

The timeout duration that was exceeded

TotalTimeout

Total operation timed out (including retries).

Fields

operation: String

The operation that timed out

timeout: Duration

The timeout duration that was exceeded

ReadTimeout

Read operation timed out (streaming).

Fields

operation: String

The operation that timed out

timeout: Duration

The timeout duration that was exceeded

ConfigurationError(String)

The transport was configured with invalid parameters.

AuthenticationFailed(String)

Authentication with the remote endpoint failed.

RateLimitExceeded

The request was rejected due to rate limiting.

NotAvailable(String)

The requested transport is not available.

Io(String)

An underlying I/O error occurred.

Internal(String)

An unexpected internal error occurred.

RequestTooLarge

Request size exceeds the configured maximum limit.

Fields

size: usize

The actual size of the request in bytes

max: usize

The maximum allowed size in bytes

ResponseTooLarge

Response size exceeds the configured maximum limit.

Fields

size: usize

The actual size of the response in bytes

max: usize

The maximum allowed size in bytes

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<(), Error>

Formats the value using the given formatter.

impl Display for TransportError

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

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<Error> for TransportError

fn from(err: Error) -> TransportError

Converts to this type from the input type.

impl From<Error> for TransportError

fn from(err: Error) -> TransportError

Converts to this type from the input type.

impl From<McpError> for TransportError

fn from(err: McpError) -> TransportError

Converts to this type from the input type.
