Struct Signal 

pub struct Signal { /* private fields */ }

The Signal struct represents a valid signal.

Implementations

impl Signal

pub const NUM_SIGNALS: u32 = 64u32

The number of signals, also the highest valid signal number.

pub fn number(&self) -> u32

The signal number, guaranteed to be a value between 1..=NUM_SIGNALS.

pub const fn mask(&self) -> u64

Returns the bitmask for this signal number.

pub fn is_real_time(&self) -> bool

Returns true if the signal is a real-time signal.

pub fn is_unblockable(&self) -> bool

Returns true if this signal can’t be blocked. This means either SIGKILL or SIGSTOP.

pub fn set_ptrace_syscall_bit(&mut self)

Used exclusively for PTRACE_O_TRACESYSGOOD

Trait Implementations

impl Clone for Signal

fn clone(&self) -> Signal

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Signal

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

Formats the value using the given formatter.

impl Display for Signal

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

Formats the value using the given formatter.

impl From<Signal> for SigSet

fn from(value: Signal) -> Self

Constructs a sigset consisting of one signal value.

impl From<Signal> for UncheckedSignal

fn from(signal: Signal) -> UncheckedSignal

Converts to this type from the input type.

impl Hash for Signal

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for Signal

fn eq(&self, other: &Signal) -> 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.

impl TryFrom<UncheckedSignal> for Signal

type Error = Errno

The type returned in the event of a conversion error.

fn try_from(value: UncheckedSignal) -> Result<Self, Self::Error>

Performs the conversion.

impl Copy for Signal

impl Eq for Signal

impl StructuralPartialEq for Signal
