Implementations§

source§

impl SignalKind

source

pub const fn from_raw(signum: i32) -> SignalKind

Allows for listening to any valid OS signal.

For example, this can be used for listening for platform-specific signals.

// let signum = libc::OS_SPECIFIC_SIGNAL;
let kind = SignalKind::from_raw(signum);
source

pub const fn as_raw_value(&self) -> i32

Get the signal’s numeric value.

let kind = SignalKind::interrupt();
assert_eq!(kind.as_raw_value(), libc::SIGINT);
source

pub const fn alarm() -> SignalKind

Represents the SIGALRM signal.

On Unix systems this signal is sent when a real-time timer has expired. By default, the process is terminated by this signal.

source

pub const fn child() -> SignalKind

Represents the SIGCHLD signal.

On Unix systems this signal is sent when the status of a child process has changed. By default, this signal is ignored.

source

pub const fn hangup() -> SignalKind

Represents the SIGHUP signal.

On Unix systems this signal is sent when the terminal is disconnected. By default, the process is terminated by this signal.

source

pub const fn interrupt() -> SignalKind

Represents the SIGINT signal.

On Unix systems this signal is sent to interrupt a program. By default, the process is terminated by this signal.

source

pub const fn io() -> SignalKind

Represents the SIGIO signal.

On Unix systems this signal is sent when I/O operations are possible on some file descriptor. By default, this signal is ignored.

source

pub const fn pipe() -> SignalKind

Represents the SIGPIPE signal.

On Unix systems this signal is sent when the process attempts to write to a pipe which has no reader. By default, the process is terminated by this signal.

source

pub const fn quit() -> SignalKind

Represents the SIGQUIT signal.

On Unix systems this signal is sent to issue a shutdown of the process, after which the OS will dump the process core. By default, the process is terminated by this signal.

source

pub const fn terminate() -> SignalKind

Represents the SIGTERM signal.

On Unix systems this signal is sent to issue a shutdown of the process. By default, the process is terminated by this signal.

source

pub const fn user_defined1() -> SignalKind

Represents the SIGUSR1 signal.

On Unix systems this is a user defined signal. By default, the process is terminated by this signal.

source

pub const fn user_defined2() -> SignalKind

Represents the SIGUSR2 signal.

On Unix systems this is a user defined signal. By default, the process is terminated by this signal.

source

pub const fn window_change() -> SignalKind

Represents the SIGWINCH signal.

On Unix systems this signal is sent when the terminal window is resized. By default, this signal is ignored.
