Enum SetHandlerError

pub enum SetHandlerError {
    UnsafeSignal,
    UnblockableSignal(SignalType),
    RealTimeSignalOutOfBounds {
        attempted: u32,
        max: u32,
    },
    UnexpectedSystemCallFailure(Error),
}

Available on Unix and crate feature signals only.

The error produced when setting a signal handler fails.

Variants

UnsafeSignal

An unsafe signal was attempted to be handled using set instead of set_unsafe.

UnblockableSignal(SignalType)

The signal which was attempted to be handled is not allowed to be handled by the POSIX specification. This can either be ForceSuspend or Kill.

RealTimeSignalOutOfBounds

The specified real-time signal is not available on this OS.

Fields

attempted: u32

The realtime signal which was attempted to be used.

max: u32

The highest available realtime signal number.

UnexpectedSystemCallFailure(Error)

An unexpected OS error ocurred during signal handler setup.

Trait Implementations

impl Debug for SetHandlerError

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

Formats the value using the given formatter.

impl Display for SetHandlerError

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

Formats the value using the given formatter.

impl Error for SetHandlerError

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 SetHandlerError

fn from(source: Error) -> Self

Converts to this type from the input type.
