Enum ExecutorError 

pub enum ExecutorError<E> {
    TaskFailed(E),
    Panic(CallbackError),
    PrepareFailed(CallbackError),
    PrepareCommitFailed(CallbackError),
    PrepareRollbackFailed {
        original: CallbackError,
        rollback: CallbackError,
    },
}

Executor error types.

Type Parameters

• E - The original error type from task execution

Examples

use qubit_dcl::double_checked::ExecutorError;
use qubit_dcl::double_checked::CallbackError;

let error: ExecutorError<String> =
    ExecutorError::TaskFailed("task failed".to_string());
println!("Error: {}", error);

let error_with_msg: ExecutorError<String> =
    ExecutorError::PrepareFailed(CallbackError::from_display("Service is not running"));
println!("Error: {}", error_with_msg);

Variants

TaskFailed(E)

Task execution failed with original error

Panic(CallbackError)

Task execution panicked.

PrepareFailed(CallbackError)

Preparation action failed

PrepareCommitFailed(CallbackError)

Commit action for a successfully completed prepare action failed.

PrepareRollbackFailed

Rollback action for a successfully completed prepare action failed.

Fields

original: CallbackError

The original error that triggered the rollback

rollback: CallbackError

The error that occurred during prepare rollback

Implementations

impl<E> ExecutorError<E>

pub fn callback_type(&self) -> Option<&'static str>

Returns the callback type label, when the error comes from a callback and the type is available.

This returns None for task failures and callback errors without associated type labels.

Trait Implementations

impl<E: Debug> Debug for ExecutorError<E>

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

Formats the value using the given formatter.

impl<E> Display for ExecutorError<E>

where E: Display,

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

Formats this executor error for user-facing diagnostics.

Parameters

• f - Formatter receiving the human-readable error text.

Returns

fmt::Result from writing the formatted error text.

impl<E> Error for ExecutorError<E>

where E: Error + 'static,

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the underlying task error as the standard error source.

Prepare lifecycle failures store their messages as strings and therefore do not expose a structured source error.

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.
