Enum ExchangeError 

pub enum ExchangeError {
    InvalidRank {
        rank: usize,
    },
    SerdeError(Error),
    IoError(Error),
    MessageTooLarge(usize),
    Timeout,
}

An error that can occur during a TCP-based endpoint exchange.

Variants

InvalidRank

A rank referenced during the exchange is not present in the NetworkConfig.

Fields

rank: usize

SerdeError(Error)

A message could not be serialized or deserialized.

IoError(Error)

An underlying TCP I/O operation failed.

MessageTooLarge(usize)

The serialized message exceeds u32::MAX bytes and cannot be framed with the 4-byte length prefix used by the wire protocol. The field contains the actual encoded size in bytes.

Timeout

The exchange did not complete within ExchangeConfig::exchange_timeout.

Trait Implementations

impl Debug for ExchangeError

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

Formats the value using the given formatter.

impl Display for ExchangeError

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

Formats the value using the given formatter.

impl Error for ExchangeError

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.

fn from(source: Error) -> Self
