Enum CallableStatusUnknownError

pub enum CallableStatusUnknownError {
    ParentPipeCloseFailed(Error),
    WaitFailed(Error),
    ParentPipeReadFailed(Error),
    CallableProcessDiedDuringExecution,
    UnexpectedChildExitStatus(i32),
    ChildProcessKilledBySignal(i32),
    UnexpectedWaitpidReturnValue(i32),
}

An error indicating that something went wrong in a way where it is difficult or impossible to determine whether the user-supplied callable was executed ¯\_(ツ)_/¯

You should only retry the callable if it is idempotent.

Variants

ParentPipeCloseFailed(Error)

A system error occurred while closing the parent’s copy of the pipe’s write end

WaitFailed(Error)

A system error occurred while waiting for the child process to exit

ParentPipeReadFailed(Error)

A system error occurred while reading the child’s result from the pipe

CallableProcessDiedDuringExecution

The callable process died while executing the user-supplied callable

UnexpectedChildExitStatus(i32)

The child process responsible for executing the user-supplied callable exited with an unexpected status

Note this does not represent some sort of exit code or return value indicating the success or failure of the user-supplied callable itself.

ChildProcessKilledBySignal(i32)

The child process responsible for executing the user-supplied callable was killed by a signal

UnexpectedWaitpidReturnValue(i32)

Waitpid returned an unexpected value

Trait Implementations

impl Error for CallableStatusUnknownError

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

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.
