Enum ConnectError 

#[non_exhaustive]
pub enum ConnectError {
    ConnectTimeout,
    PermissionDenied,
    EndpointTooLong,
    Failed(ErrorKind),
}

Connection establishment failure, before application traffic is sent.

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.

ConnectTimeout

Nothing accepted the connection in time: the endpoint does not exist yet, refused the connection, is busy, or the deadline passed.

PermissionDenied

The OS denied access to the endpoint.

EndpointTooLong

The endpoint path does not fit in a Unix socket address, so no attempt can succeed. See crate::socket_path.

Failed(ErrorKind)

The OS failed the attempt for another reason, which waiting does not fix.

Implementations

impl ConnectError

pub fn is_transient(&self) -> bool

Whether a later attempt can succeed: nothing accepted the connection in time, which includes an endpoint that does not exist yet. Every failure is_transient lists becomes Self::ConnectTimeout.

Trait Implementations

impl Clone for ConnectError

fn clone(&self) -> Self

Returns a duplicate of the value.

impl Eq for ConnectError

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 PartialEq for ConnectError

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

Equality operator ==.

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

Inequality operator !=.
