Enum libzmq::ErrorKind

#[non_exhaustive]pub enum ErrorKind {
    WouldBlock,
    HostUnreachable,
    InvalidCtx,
    Interrupted,
    AddrInUse,
    AddrNotAvailable,
    NotFound(&'static str),
    SocketLimit,
    InvalidInput(&'static str),
}

Used to give context to an Error.

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.

WouldBlock

Non-blocking mode was requested and the message cannot be sent without blocking

HostUnreachable

Occurs when a Server socket cannot route a message to a host.

InvalidCtx

The context used in the operation was invalidated. Either the context is being terminated, or was already terminated.

This error only occurs if:

• The Ctx is being dropped or was previously dropped.
• shutdown was called.

Interrupted

The operation was interrupted by a OS signal delivery.

AddrInUse

The addr cannot be bound because it is already in use.

AddrNotAvailable

A nonexistent interface was requested or the requested address was not local.

NotFound(&'static str)

An entity was not found.

Contains information on the specific entity.

SocketLimit

The open socket limit was reached.

InvalidInput(&'static str)

The user did not follow its usage contract and provided invalid inputs.

Contains information on the specific contract breach.

Trait Implementations

impl Clone for ErrorKind

fn clone(&self) -> ErrorKind

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for ErrorKind

impl Debug for ErrorKind

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

Formats the value using the given formatter.

impl Display for ErrorKind

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

Formats the value using the given formatter.

impl Eq for ErrorKind

impl Error for ErrorKind

fn source(&self) -> Option<&(dyn Error + 'static)>

The lower-level source of this error, if any.

fn backtrace(&self) -> Option<&Backtrace>

🔬 This is a nightly-only experimental API. (backtrace)

Returns a stack backtrace, if available, of where this error occurred.

fn description(&self) -> &str

Deprecated since 1.42.0:

use the Display impl or to_string()

if let Err(e) = "xc".parse::<u32>() { // Print e itself, no need for description(). eprintln!("Error: {}", e); }

fn cause(&self) -> Option<&dyn Error>

Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

impl Hash for ErrorKind

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given [Hasher].

fn hash_slice<H>(data: &[Self], state: &mut H) where
    H: Hasher, 

Feeds a slice of this type into the given [Hasher].

impl PartialEq<ErrorKind> for ErrorKind

fn eq(&self, other: &ErrorKind) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &ErrorKind) -> bool

This method tests for !=.
