Struct SignalSetBuilder

pub struct SignalSetBuilder { /* private fields */ }

Available on Unix only.

Constructs a SignalSet using the builder pattern.

Signals that cannot be handled are not listed as methods.

Implementations

impl SignalSetBuilder

pub fn new() -> Self

Creates a new, empty signal set builder.

pub const unsafe fn from_raw(signal_set: Opaque) -> Self

Creates a new builder from the raw signal_set.

Safety

This library assumes that all signals used are valid. Supplying an unsupported signal set invalidates this assumption.

pub const fn into_raw(self) -> Opaque

Returns the raw value of this signal set builder.

pub fn termination_set(self) -> Self

The set of signals that result in process termination.

pub fn alarm(self) -> Self

The SIGALRM signal; sent when a real-time timer expires.

Default behavior: process termination.

pub fn child(self) -> Self

The SIGCHLD signal; sent when the status of a child process changes.

Default behavior: ignored.

pub fn hangup(self) -> Self

The SIGHUP signal; sent when the terminal is disconnected.

Default behavior: process termination.

pub fn info(self) -> Self

The SIGINFO signal; sent to request a status update from the process.

Not supported on: android, emscripten, linux.

Keyboard shortcut: CTRL + T.

Default behavior: ignored.

pub fn interrupt(self) -> Self

The SIGINT signal; sent to interrupt a program.

Keyboard shortcut: CTRL + C.

Default behavior: process termination.

pub fn io(self) -> Self

The SIGIO signal; sent when I/O operations are possible on some file descriptor.

Default behavior: ignored.

pub fn pipe(self) -> Self

The SIGPIPE signal; sent when the process attempts to write to a pipe which has no reader.

Default behavior: process termination.

pub fn quit(self) -> Self

The SIGQUIT signal; sent to issue a shutdown of the process, after which the OS will dump the process core.

Keyboard shortcut: CTRL + \.

Default behavior: process termination.

pub fn terminate(self) -> Self

The SIGTERM signal; sent to issue a shutdown of the process.

Default behavior: process termination.

pub fn user_defined_1(self) -> Self

The SIGUSR1 signal; a user defined signal.

Default behavior: process termination.

pub fn user_defined_2(self) -> Self

The SIGUSR2 signal; a user defined signal.

Default behavior: process termination.

pub fn window_change(self) -> Self

The SIGWINCH signal; sent when the terminal window is resized.

Default behavior: ignored.

pub fn with(self, signal: SignalKind) -> Self

Returns self with signal added to it.

pub fn insert(&mut self, signal: SignalKind)

Adds signal to self.
