Struct LinuxSigset 

#[repr(C)]
pub struct LinuxSigset {
    pub sig: [c_size_t; 1],
}

Available on crate feature linux only.

🐧 📶 ⊆ 🔻 A raw Linux kernel signal mask.

^{📍 sys/os/linux/process}

^{📦 size_of::<LinuxSigset>() == 4 bytes / 32 bits #️⃣ #[cfg(target_pointer_width = “32”)]}

^{📦 size_of::<LinuxSigset>() == 8 bytes / 64 bits #️⃣ #[cfg(target_pointer_width = “64”)]}

---

This is the mask representation passed to raw Linux signal syscalls.

Signal numbers start at 1, while mask bits start at 0, so signal n is stored in bit n - 1.

For the semantic Devela set, use LinuxSignalSet.

Fields

sig: [c_size_t; 1]

Raw signal mask words.

Implementations

impl LinuxSigset

pub const WORD_BITS: usize

Number of bits in one raw mask word.

pub const MAX_SIGNAL: usize

pub const WORDS: usize

Number of raw mask words needed for the supported signal range.

pub const fn empty() -> Self

Returns an empty signal mask.

pub const fn size() -> c_size_t

Returns the size in bytes passed to raw Linux signal syscalls.

pub const fn from_signal_set(signals: LinuxSignalSet) -> Self

Returns a raw mask from a semantic signal set.

pub const fn to_signal_set(self) -> LinuxSignalSet

Returns this raw mask as a semantic signal set.

pub const fn with_signal(self, signal: LinuxSignal) -> Self

Returns a copy with signal added.

pub const fn without_signal(self, signal: LinuxSignal) -> Self

Returns a copy with signal removed.

Ignores unsupported signal numbers.

pub const fn has_signal(self, signal: LinuxSignal) -> bool

Returns whether this raw mask contains signal.

pub fn insert_signal(&mut self, signal: LinuxSignal)

Adds signal to this raw mask.

pub fn remove_signal(&mut self, signal: LinuxSignal)

Removes signal from this raw mask.

Panics

Panics if signal is not a supported standard Linux signal.

pub const fn with_signal_number(self, signal: c_int) -> Self

Returns a copy with the raw signal number added, if supported.

Trait Implementations

impl Clone for LinuxSigset

fn clone(&self) -> LinuxSigset

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for LinuxSigset

impl Debug for LinuxSigset

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

Formats the value using the given formatter.

impl Default for LinuxSigset

fn default() -> LinuxSigset

Returns the “default value” for a type.

impl Eq for LinuxSigset

impl From<LinuxSignalSet> for LinuxSigset

fn from(signals: LinuxSignalSet) -> Self

Converts to this type from the input type.

impl From<LinuxSigset> for LinuxSignalSet

fn from(mask: LinuxSigset) -> Self

Converts to this type from the input type.

impl Hash for LinuxSigset

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 Ord for LinuxSigset

fn cmp(&self, other: &LinuxSigset) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for LinuxSigset

fn eq(&self, other: &LinuxSigset) -> 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 PartialOrd for LinuxSigset

fn partial_cmp(&self, other: &LinuxSigset) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
