Struct Signal

Source

pub struct Signal(/* private fields */);

Expand description

A signal number for use with kill_process, kill_process_group, and kill_current_process_group.

For additional constructors such as Signal::rt_min (aka libc::SIGRTMIN), Signal::rt_max (aka libc::SIGRTMAX), Signal::rt (aka |n| libc::SIGRTMIN() + n), Signal::from_raw, and Signal::from_raw_nonzero, see rustix-libc-wrappers.

impl Signal

Source

pub const fn as_raw(self) -> i32

Convert a Signal to a raw signal number.

To convert to a NonZeroI32, use Signal::as_raw_nonzero.

Source

pub const fn as_raw_nonzero(self) -> NonZeroI32

Convert a Signal to a raw non-zero signal number.

Source

pub const unsafe fn from_raw_unchecked(sig: i32) -> Self

Convert a raw signal number into a Signal without checks.

For a safe checked version, see Signal::from_raw in rustix-libc-wrappers.

§Safety

sig must be a valid and non-zero signal number.

And, if sig is a signal number reserved by the libc, such as a value from the libc SIGRTMIN to the libc SIGRTMAX, inclusive, then the resulting Signal must not be used to send, consume, or block any signals or alter any signal handlers.

Source

pub const unsafe fn from_raw_nonzero_unchecked(sig: NonZeroI32) -> Self

Convert a raw non-zero signal number into a Signal without checks.

For a safe checked version, see Signal::from_raw_nonzero in rustix-libc-wrappers.

§Safety

sig must be a valid signal number.

And, if sig is a signal number reserved by the libc, such as a value from SIGRTMIN to SIGRTMAX inclusive, then the resulting Signal must not be used to send, consume, or block any signals or alter any signal handlers.

Source

pub const fn from_named_raw(sig: i32) -> Option<Self>

Convert a raw named signal number into a Signal.

If the given signal number corresponds to one of the named constant signal values, such as Signal::HUP or Signal::INT, return the Signal value. Otherwise return None.

Signals in the range SIGRTMIN through SIGRTMAX are not supported by this function. For a constructor that does recognize those values, see Signal::from_raw in rustix-libc-wrappers.

Source

pub const fn from_named_raw_nonzero(sig: NonZeroI32) -> Option<Self>

Convert a raw non-zero named signal number into a Signal.

If the given signal number corresponds to one of the constant signal values, such as Signal::HUP or Signal::INT, return the Signal value. Otherwise return None.

Signals in the range SIGRTMIN through SIGRTMAX are not supported by this function. For a constructor that does recognize those values, see Signal::from_raw_nonzero in rustix-libc-wrappers.
