Enum ZmqError 

#[non_exhaustive]
pub enum ZmqError {
    Endpoint {
        endpoint: String,
        source: Box<dyn StdError + Send + Sync>,
    },
    Send {
        name: String,
        reason: String,
    },
    Receive(String),
    Wire(String),
    RequestTimeout,
    NotConnected,
    Invalid(String),
}

Errors returned by the ZeroMQ transport.

One enum for the whole crate, variants by source, per the RustStream broker conventions. The wrapped sources are boxed std errors so the public API does not leak the implementation’s error types.

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.

Endpoint

Binding or connecting a socket failed.

Fields

endpoint: String

The endpoint the socket targeted.

source: Box<dyn StdError + Send + Sync>

The implementation’s failure.

Send

Sending failed (no connected peer after the retry window, or the transport failed).

Fields

name: String

The message name the send targeted.

reason: String

The failure reason.

Receive(String)

Receiving failed.

Wire(String)

A peer sent frames that do not follow the documented wire layout.

RequestTimeout

A request did not produce a reply within the caller’s timeout.

NotConnected

The handle is used before connect filled the shared state, or after shutdown.

Invalid(String)

An endpoint or descriptor is invalid.

Trait Implementations

impl Debug for ZmqError

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

Formats the value using the given formatter.

impl Display for ZmqError

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

Formats the value using the given formatter.

impl Error for ZmqError

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.
