Enum SignalAction 

pub enum SignalAction {
    Noop,
    LogLevelUp,
    LogLevelDown,
    ReopenLog,
    Shutdown,
    StackTrace,
    Ignore,
}

Action to run when a signal is delivered.

The default mapping is: SIGTTIN/SIGTTOU adjust the global log verbosity, SIGHUP reopens the log file, SIGINT requests a graceful shutdown, SIGUSR1 and SIGUSR2 are reserved noop slots, SIGSEGV records a stack trace, and SIGPIPE is ignored.

Examples

use dynomite::core::signal::SignalAction;
assert_ne!(SignalAction::Shutdown, SignalAction::Noop);
assert_eq!(SignalAction::Ignore, SignalAction::Ignore);

Variants

Noop

Reserved slot used by the in-process action table that currently does nothing.

LogLevelUp

Bump the global log verbosity by one.

LogLevelDown

Drop the global log verbosity by one.

ReopenLog

Reopen the active log file (if any).

Shutdown

Request a graceful shutdown.

StackTrace

Print a stack trace; the dispatcher also re-raises SIGSEGV afterwards so the kernel can produce the standard core dump.

Ignore

Ignore the signal entirely (matches SIG_IGN).

Trait Implementations

impl Clone for SignalAction

fn clone(&self) -> SignalAction

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for SignalAction

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

Formats the value using the given formatter.

impl PartialEq for SignalAction

fn eq(&self, other: &SignalAction) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
