Enum SigHandler 

pub enum SigHandler {
    SigDfl,
    SigIgn,
    Handler(extern "C" fn(i32)),
    SigAction(extern "C" fn(i32, *mut siginfo_t, *mut c_void)),
}

A signal handler.

Variants

SigDfl

Default signal handling.

SigIgn

Request that the signal be ignored.

Handler(extern "C" fn(i32))

Use the given signal-catching function, which takes in the signal.

SigAction(extern "C" fn(i32, *mut siginfo_t, *mut c_void))

Use the given signal-catching function, which takes in the signal, information about how the signal was generated, and a pointer to the threads ucontext_t.

Trait Implementations

impl Clone for SigHandler

fn clone(&self) -> SigHandler

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SigHandler

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

Formats the value using the given formatter.

impl Hash for SigHandler

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for SigHandler

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

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

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

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