Enum Error 

pub enum Error {
    Io(Error),
    Serialize(String),
    Deserialize(String),
    Protocol(String),
    Auth(String),
    ConnectionClosed,
    Cancelled,
    UnsupportedCapability,
}

An error from session establishment, transport, or an individual call.

Variants

Io(Error)

The underlying transport failed.

Serialize(String)

Serializing an outgoing request or response failed.

Deserialize(String)

Deserializing an incoming request or response failed.

Protocol(String)

The peer sent data that violates the RPC protocol.

Auth(String)

A pre-shared key was rejected, missing, or unexpected.

Covers both a locally supplied key that cannot be used (see AuthKey::new) and a peer that failed the check during negotiation. The message never includes key material.

ConnectionClosed

The local or peer session closed before the operation completed.

Cancelled

The peer cancelled this call before it received a response.

UnsupportedCapability

A requested transport capability is unavailable.

Returned when an OsHandle is serialized over a session whose transport cannot carry handle attachments (a generic byte-stream transport rather than a Unix-domain socket or a Windows named pipe).

Trait Implementations

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

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 Error

fn from(source: Error) -> Self

Converts to this type from the input type.
