Enum HttpError 

pub enum HttpError {
    Connect(Error),
    Http(Error),
    Status(u16, Vec<u8>),
    Unsupported(String),
    NoResponse,
}

An MCP transport error (connect / HTTP / protocol).

Variants

Connect(Error)

Http(Error)

Status(u16, Vec<u8>)

A non-2xx HTTP status, with the (capped) response body — carried so the caller can classify a modern JSON-RPC error (era detection, -32022 version retry) from the body rather than just the status code.

Unsupported(String)

The build lacks the feature this endpoint needs (e.g. vsock).

NoResponse

No JSON-RPC response matched the request id before the stream ended.

Trait Implementations

impl Debug for HttpError

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

impl Display for HttpError

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

Formats the value using the given formatter.

impl Error for HttpError

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>)
