Enum interprocess_docfix::os::windows::signal::SignalHandler

pub enum SignalHandler {
    Default,
    Ignore,
    Hook(SignalHook),
    NoReturnHook(NoReturnSignalHook),
}

Available on Windows and crate feature signals only.

A signal handling method.

Variants

Default

Use the default behavior specified by the C standard.

Ignore

Ignore the signal whenever it is received.

Hook(SignalHook)

Call a function whenever the signal is received. The function can return, execution will continue.

NoReturnHook(NoReturnSignalHook)

Call a function whenever the signal is received. The function must not return.

Implementations

impl SignalHandler

pub const fn is_default(self) -> bool

Returns true for the Default variant, false otherwise.

pub const fn is_ignore(self) -> bool

Returns true for the Ignore variant, false otherwise.

pub const fn is_hook(self) -> bool

Returns true for the Hook and NoReturnHook variants, false otherwise.

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

Creates a handler 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 unsafe fn from_fn_noreturn(function: fn() -> !) -> Self

Creates a handler which calls the specified function and is known to never return.

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.

Trait Implementations

impl Clone for SignalHandler

fn clone(&self) -> SignalHandler

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for SignalHandler

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

Formats the value using the given formatter.

impl Default for SignalHandler

fn default() -> Self

Returns SignalHandler::Default.

impl PartialEq<SignalHandler> for SignalHandler

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

This method tests for self and other values to be equal, and is used by ==.

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

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