Errors that can occur inside the scheduler subsystem.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

InvalidCron(String)

The provided cron expression could not be parsed.

The inner string contains the original expression and the parser’s error message.

Database(SqlxError)

A low-level SQLx error occurred during a database operation.

Db(DbError)

A high-level zeph-db error occurred (e.g. during migrations or connection setup).

TaskFailed(String)

The crate::TaskHandler returned an error during task execution.

The inner string is the human-readable description from the handler.

DuplicateJob(String)

A job with the given name already exists in the store.

Returned by crate::JobStore::insert_job on a UNIQUE constraint violation.

Detach(String)

Failed to detach the daemon process (fork, exec, or I/O redirection error).

Io(String)

A generic I/O error from daemon lifecycle operations (pid file, log file).

PromptInjectionBlocked

A task prompt matched an injection pattern and was blocked by the RTW-A defense.

The task is skipped for this tick and logged at WARN level. No prompt is forwarded to the agent loop.

Fields

task_name: String

Name of the task whose prompt was blocked.

reason: String

Description of the pattern that triggered the block.

TaskQuarantined

A task was quarantined by the RTW-A write-fence and skipped for this tick.

Tasks written to the store in the same tick they would execute are held back for one tick to prevent write-before-exposed-read re-entry attacks.

Fields

task_name: String

Name of the task that was quarantined.

Trait Implementations

impl Debug for SchedulerError

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

Formats the value using the given formatter.

impl Display for SchedulerError

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

Formats the value using the given formatter.

impl Error for SchedulerError

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<DbError> for SchedulerError

fn from(source: DbError) -> Self

Converts to this type from the input type.

impl From<Error> for SchedulerError

fn from(source: SqlxError) -> Self

Converts to this type from the input type.
