Enum SocketError

pub enum SocketError {
    IO(Error),
    WrongPID(u32, String),
    NotSocket(RawFd),
    MissingVar(&'static str),
    InvalidVar(&'static str, String),
}

Errors that can occur when trying to access systemd-owned sockets

Variants

IO(Error)

An IO error occurred communicating with the socket

WrongPID(u32, String)

The PID that systemd gave us is not our PID

NotSocket(RawFd)

The file descriptor that systemd gave us is not a socket

MissingVar(&'static str)

Missing a systemd variable

InvalidVar(&'static str, String)

Invalid value for a systemd variable

Trait Implementations

impl Debug for SocketError

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

Formats the value using the given formatter.

impl Display for SocketError

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

Formats the value using the given formatter.

impl Error for SocketError

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 SocketError

fn from(source: Error) -> Self

Converts to this type from the input type.

impl From<SocketError> for NotifyError

fn from(value: SocketError) -> Self

Converts to this type from the input type.
