Failure from a future DuplicateHandle handoff attempt.

Variants

UnsupportedPlatform

The current target cannot use the Windows handoff transport.

CannotOpenBackend

Opening the backend process for PROCESS_DUP_HANDLE failed.

Fields

backend_pid: u32

Backend process ID that could not be opened.

PermissionDenied

The platform denied handle duplication.

Fields

backend_pid: u32

Backend process ID targeted by the handoff.

DuplicateFailed

DuplicateHandle failed after the backend process was opened.

Fields

backend_pid: u32

Backend process ID targeted by the handoff.

raw_os_error: Option<i32>

Raw Windows error code returned by the platform, when available.

IntegrityMismatch

The broker and backend trust or integrity levels are incompatible.

Fields

backend_pid: u32

Backend process ID targeted by the handoff.

BackendAckTimeout

The backend did not acknowledge the duplicated handle before the deadline.

Fields

backend_pid: u32

Backend process ID targeted by the handoff.

Implementations

impl DuplicateHandleError

pub fn attempt_failure(&self) -> Option<HandoffAttemptFailure>

Return the existing attempt-failure classification, when this was a real attempt.

pub fn fallback_reason(&self) -> HandoffFallbackReason

Map this transport failure into the existing fallback reason vocabulary.

pub fn fallback_decision(&self) -> HandoffFallbackDecision

Return the silent reconnect fallback for this transport failure.

pub fn fallback_attempt_decision(&self) -> HandoffAttemptDecision

Return the full attempt decision for callers that operate on broker decisions.

pub fn is_fallback_safe(&self) -> bool

Return true when this error is safe to hide behind reconnect fallback.

Trait Implementations

impl Clone for DuplicateHandleError

fn clone(&self) -> DuplicateHandleError

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for DuplicateHandleError

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

Formats the value using the given formatter.

impl Display for DuplicateHandleError

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

Formats the value using the given formatter.

impl Eq for DuplicateHandleError

impl Error for DuplicateHandleError

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 DuplicateHandleError

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
