Enum HandoffError 

#[non_exhaustive]
pub enum HandoffError {
    PeerMismatch,
    Truncated,
    CountMismatch,
    BadMagic,
    BadVersion,
    BadChecksum,

}

Why a listener hand-off failed. Nothing is adopted on any error.

assert_eq!(net_io::HandoffError::BadChecksum.to_string(), "the hand-off manifest checksum does not match");

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.

PeerMismatch

The sender is not the expected process or user.

Truncated

The control message was truncated.

CountMismatch

The descriptor count does not match the manifest.

BadMagic

The manifest does not start with the expected magic.

BadVersion

The manifest version is unknown.

BadChecksum

The manifest checksum does not match.

TooMany

More listeners than one hand-off carries.

Fields

max: u8

The maximum.

VerifyFailed

A received socket failed verification.

Fields

index: u8

Its position in the manifest.

why: &'static str

Which check failed.

Timeout

The hand-off did not finish in time.

Os(Error)

An OS call failed.

Trait Implementations

impl Debug for HandoffError

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

Formats the value using the given formatter.

impl Display for HandoffError

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

Formats the value using the given formatter.

impl Error for HandoffError

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.
