Enum ExecutorError 

pub enum ExecutorError<E>
where
    E: Display,
{
    TaskFailed(E),
    PrepareFailed(String),
    PrepareCommitFailed(String),
    PrepareRollbackFailed {
        original: String,
        rollback: String,
    },
    LockPoisoned(String),
}

Executor error types

Defines various error conditions that can occur during executor operation, including task execution errors, prepare failures, prepare commit failures, and prepare rollback failures.

Type Parameters

• E - The original error type from task execution

Examples

use qubit_dcl::double_checked::ExecutorError;

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

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

Trait Implementations

impl<E> Debug for ExecutorError<E>

where E: Display + Debug,

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: Display + Debug,

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.
