Enum SchedulerError 

pub enum SchedulerError {
    InvalidCron(String),
    Database(SqlxError),
    Db(DbError),
    TaskFailed(String),
    DuplicateJob(String),
    AlreadyRunning {
        pid: u32,
    },
    Detach(String),
    Io(String),
}

Errors that can occur inside the scheduler subsystem.

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.

AlreadyRunning

Another zeph serve instance is already running with the given PID.

Returned by [crate::PidFile::acquire] when the pid file is locked by another process.

Fields

pid: u32

PID of the running daemon, as stored in the pid file.

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).

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.
