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.

ServerNotFound

The named MCP server was not found in the client.

Fields

name: String

Server name that was not found.

Transport

A transport-level error occurred (connection, I/O, protocol).

Fields

message: String

Description of the transport error.

ConnectionFailed

Failed to establish a connection to the server.

Fields

server: String

Server name.

reason: String

Reason for the connection failure.

Timeout

A request exceeded the configured timeout.

Fields

server: String

Server name where the timeout occurred.

ToolNotFound

The requested tool was not found on any connected server.

Fields

name: String

Tool name that was not found.

SchemaValidation

JSON Schema validation of tool arguments failed.

Fields

tool: String

Tool name for which validation failed.

reason: String

Validation failure details.

UnsupportedContent

The MCP server returned a content type that is not supported.

Fields

content_type: String

The unsupported content type identifier.

InterceptorPanic

An interceptor panicked during execution.

Fields

message: String

Panic message captured via catch_unwind.

Serialization(Error)

Serialization or deserialization error.

Trait Implementations

impl Debug for McpAdapterError

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

Formats the value using the given formatter.

impl Display for McpAdapterError

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

Formats the value using the given formatter.

impl Error for McpAdapterError

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 McpAdapterError

fn from(source: Error) -> Self

Converts to this type from the input type.
