Struct SignalHook

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

Available on Unix and crate feature signals only.

A function which can be used as a signal handler.

Implementations

impl SignalHook

pub unsafe fn from_fn(function: fn()) -> Self

Creates a hook which calls the specified function.

Safety

The function must not call any C functions which are not considered signal-safe. See the module-level section on signal-safe C functions for more.

pub fn inner(self) -> fn()

Returns the wrapped function.

Trait Implementations

impl Clone for SignalHook

fn clone(&self) -> SignalHook

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SignalHook

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

Formats the value using the given formatter.

impl From<SignalHook> for SignalHandler

fn from(op: SignalHook) -> Self

Converts to this type from the input type.

impl From<SignalHook> for fn()

fn from(op: SignalHook) -> Self

Converts to this type from the input type.

impl PartialEq for SignalHook

fn eq(&self, other: &SignalHook) -> bool

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
