Enum LoopError 

pub enum LoopError {
    Io(Error),
    Journal(String),
    Queue(String),
    Pause {
        policy: String,
        detail: String,
    },
    Dispatch(String),
    Config(String),
}

Errors returned by the loop runtime.

Variants

Io(Error)

I/O failure (file open, read, write).

Journal(String)

Journal write to the project events file failed (fatal per spec).

Queue(String)

Queue operation failed.

Pause

Walk policy requests a pause. Not a true error: run_loop maps it to a walk_paused journal event + TerminationReason::NoProgress. Kept distinct from Queue so a real queue error whose message happens to start with pause: can never be misrouted to the pause path. Structural twin of NextStep::Pause, carrying the same typed policy/detail.

Fields

policy: String

detail: String

Dispatch(String)

Dispatcher operation failed.

Config(String)

Configuration error (e.g., invalid budget).

Trait Implementations

impl Debug for LoopError

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

Formats the value using the given formatter.

impl Display for LoopError

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

Formats the value using the given formatter.

impl Error for LoopError

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 From<Error> for LoopError

fn from(source: Error) -> Self

Converts to this type from the input type.
