Error types for the Tcp::connect function.

Variants

MaximumConnectionsReached

Fields

limit: u16

AlreadyConnecting

Fields

address: SocketAddr

AlreadyConnected

Fields

address: SocketAddr

SelfConnect

Fields

address: SocketAddr

BannedIp

Fields

ip: IpAddr

IoError(Error)

ApplicationError(Box<dyn ApplicationError>)

Other(Box<dyn Error + Send + Sync>)

An unexpected error at the application layer and certain deserialization errors. TODO(kaimast): (some of) these should be treated with higher severity, as they indicate a bug or corrupted state, and deserialization errors should not be included in this “other” category.

Implementations

impl ConnectError

pub fn application<E: ApplicationError>(err: E) -> Self

Pass an application-level error to the Tcp stack.

pub fn other<E: Into<Box<dyn Error + Send + Sync>>>(err: E) -> Self

A generic error that can be returned by the Tcp stack.

Trait Implementations

impl Debug for ConnectError

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

Formats the value using the given formatter.

impl Display for ConnectError

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

Formats the value using the given formatter.

impl Error for ConnectError

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.

impl From<Box<dyn Error + Send + Sync>> for ConnectError

fn from(source: Box<dyn Error + Send + Sync>) -> Self

Converts to this type from the input type.

impl From<ConnectError> for Error

fn from(err: ConnectError) -> Self

Converts to this type from the input type.

impl From<Error> for ConnectError

fn from(err: Error) -> Self

Converts to this type from the input type.
