Enum psup_impl::Error

pub enum Error {
    WorkerNoId,
    WorkerNoSocket,
    WorkerNoDetached,
    Io(Error),
    Oneshot(RecvError),
    Boxed(Box<dyn Error + Send + Sync>),
}

Enumeration of errors.

Variants

WorkerNoId

Worker is missing the id environment variable.

WorkerNoSocket

Worker is missing the socket path environment variable.

WorkerNoDetached

Worker is missing the detached flag environment variable.

Io(Error)

Input/output errors.

Oneshot(RecvError)

Error whilst sending bind notifications.

Boxed(Box<dyn Error + Send + Sync>)

Generic variant for errors created in user code.

Implementations

impl Error

pub fn boxed(e: impl Error + Send + Sync + 'static) -> Self

Helper function to Box an error implementation.

Ssocket handlers can call map_err(Error::boxed)? to propagate foreign errors.

Trait Implementations

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

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

The lower-level source of this error, if any.

pub fn backtrace(&self) -> Option<&Backtrace>

🔬 This is a nightly-only experimental API. (backtrace)

Returns a stack backtrace, if available, of where this error occurred.

pub fn description(&self) -> &str

👎 Deprecated since 1.42.0:

use the Display impl or to_string()

pub fn cause(&self) -> Option<&dyn Error>

👎 Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

fn from(source: Box<dyn Error + Send + Sync>) -> Self

Performs the conversion.

impl From<Error> for Error

fn from(source: Error) -> Self

Performs the conversion.

impl From<RecvError> for Error

fn from(source: RecvError) -> Self
