Enum libzmq::ErrorKind

pub enum ErrorKind {
    WouldBlock,
    HostUnreachable,
    CtxTerminated,
    Interrupted,
    AddrInUse,
    AddrNotAvailable,
    NotFound {

    InvalidInput {

}

Used to give context to an Error.

Note

This error type is non-exhaustive and 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.

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.

CtxTerminated

The context was terminated while the operation was ongoing. Any further operations on sockets that share this context will result in this error.

This error can only occur if the Ctx was explicitely terminated.

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

An entity was not found.

The inner msg contains information on the specific entity.

Fields of NotFound

msg: &'static str

Additionnal information on the error.

SocketLimit

The open socket limit was reached.

InvalidInput

A fn call did not follow its usage contract and provided invalid inputs.

An InvalidInput error is guaranteed to be related to some API misuse that can be known at compile time. Thus panic should be called on those types of error.

The inner msg contains information on the specific contract breach.

Fields of InvalidInput

msg: &'static str

Additionnal information on the error.

Trait Implementations

impl Eq for ErrorKind

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 !=.

impl Copy for ErrorKind

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 Debug for ErrorKind

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

Formats the value using the given formatter.

impl Display for ErrorKind

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

Formats the value using the given formatter.

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 Fail for ErrorKind

fn name(&self) -> Option<&str>

Returns the "name" of the error.

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

Returns a reference to the underlying cause of this failure, if it is an error that wraps other errors.

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

Returns a reference to the Backtrace carried by this failure, if it carries one.

fn context<D>(self, context: D) -> Context<D> where
    D: Display + Send + Sync + 'static, 

Provides context for this failure.

fn compat(self) -> Compat<Self>

Wraps this failure in a compatibility wrapper that implements std::error::Error.
