Enum interprocess::os::unix::signal::SetHandlerError

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

Variants

UnsafeSignal

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

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 of RealTimeSignalOutOfBounds

attempted: u32max: u32

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)>

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

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

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

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

fn description(&self) -> &str

👎 Deprecated since 1.42.0:

use the Display impl or to_string()

if let Err(e) = "xc".parse::<u32>() { // Print e itself, no need for description(). eprintln!("Error: {}", e); }

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

👎 Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

impl From<Error> for SetHandlerError

fn from(source: Error) -> Self

Performs the conversion.
