# Struct SignalKind

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

Expand description

Represents the specific kind of signal to listen for.

## Implementations§

§

### impl SignalKind

#### 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);

#### 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);

#### 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.

#### 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.

#### 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.

#### 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.

#### 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.

#### 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.

#### 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.

#### 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.

#### 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.

#### 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.

#### 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.
