Struct HermitCleanupUnconfirmed 

pub struct HermitCleanupUnconfirmed { /* private fields */ }

Sendable diagnostic identifying an operation retained on its original thread.

This owns no runtime or tracee capability. resume::<T>() must use the exact successful return type of the original public call. Dropping this value does not release the owner or reopen ordinary admission. There is no library alarm or automatic process exit after this value is returned.

While any operation is retained, later ordinary-ptrace calls in this process refuse admission. Already admitted calls can complete. A poisoned owner or an owner whose original thread exited cannot recover; its resources are retained and admission stays closed for the process lifetime. In-process callers must explicitly supervise this condition rather than assume a failed call cleaned up or that dropping this diagnostic released the resources.

Implementations

impl HermitCleanupUnconfirmed

pub fn recovery_key(&self) -> u64

Opaque recovery key; meaningful only with the original process/thread.

pub fn stage(&self) -> HermitCleanupStage

The unresolved phase, not a guest exit status.

pub fn primary_kind(&self) -> FailureKind

Classification of the first received failure, never a secondary cause.

pub fn primary_message(&self) -> &str

A diagnostic copy. The nonclone typed cause remains with the owner.

pub fn origin(&self) -> Option<&str>

The original backend callback/operation, when one has been received.

pub fn stdout_prefix(&self) -> Option<&[u8]>

Captured stdout at this checkpoint; absent for noncapturing operations.

pub fn stderr_prefix(&self) -> Option<&[u8]>

Captured stderr at this checkpoint; absent for noncapturing operations.

pub fn callback_diagnostics(&self) -> &[PtraceCallbackDiagnostic]

Backend callback observations received before this checkpoint.

pub fn resume<T: Send + 'static>(&self) -> Result<T, Error>

Continue the SAME operation for one cooperative two-second attempt.

A further checkpoint is returned as another typed HermitCleanupUnconfirmed error. Wrong identity/type, nested runtimes, reentry and poisoned owners refuse without polling or discarding it. Synchronous kernel calls and user code cannot be preempted by this budget. If the original deadline expired before startup produced a termination handle, recovery continues that same startup and can therefore begin its effects after the deadline. As soon as the handle becomes available the already-expired timeout is published; no normal guest completion is claimed from this recovery. Do not call resume expecting cancellation of an operation that has not yet established its owned termination handle.

An operation a public launch function started lives on the calling thread’s tracer thread (crate::tracer_thread); resuming it from that caller continues it there.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()
