}

Error enum for all cases of internal/external errors occuring during client execution

Variants

CommandBuildError(String)

Building a command has failed because of invalid syntax or incorrect arguments

IOError(Error)

Generic IO error from stdlib

ServerDisconnected(Option<Error>)

Occurs when the client is not yet connected or got disconnected from the server. Contains Some<io::Error> when it’s actually a disconnection or contains None when we are not connected at all

ProtocolError(CommandError)

Protocol error

UTF8Error(FromUtf8Error)

Occurs if we try to parse a string that is supposed to be valid UTF8 and…is actually not

TlsError(Error)

Error on TLS handling

TlsHostMissingError

Occurs when the host is not provided, removing the ability for TLS to function correctly for server identify verification

UrlParseError(ParseError)

Cannot parse an URL

AddrParseError(AddrParseError)

Cannot parse an IP

UriDNSResolveError(Option<Error>)

Occurs when we cannot resolve the URI given using the local host’s DNS resolving mechanisms Will contain Some(io::Error) when the resolving has been tried with an error, and None when resolving succeeded but gave no results

CannotReconnectToServer

Cannot reconnect to server after retrying once

InnerBrokenChain

Something went wrong in one of the Reciever/Sender pairs

MaxPayloadOverflow(u32)

The user supplied a too big payload for the server

GenericError(String)

Generic string error

SubscriptionReachedMaxMsgs(u32)

Error thrown when a subscription is fused after reaching the maximum messages

Trait Implementations

impl Debug for NatsError

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

impl Fail for NatsError

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, Self: Sized,

Provides context for this failure.

fn compat(self) -> Compat<Self>

where Self: Sized,

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