Enum nix::sys::ptrace::Event

#[repr(i32)]
#[non_exhaustive]
pub enum Event {
    PTRACE_EVENT_FORK,
    PTRACE_EVENT_VFORK,
    PTRACE_EVENT_CLONE,
    PTRACE_EVENT_EXEC,
    PTRACE_EVENT_VFORK_DONE,
    PTRACE_EVENT_EXIT,
    PTRACE_EVENT_SECCOMP,
    PTRACE_EVENT_STOP,
}

Using the ptrace options the tracer can configure the tracee to stop at certain events. This enum is used to define those events as defined in man ptrace.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

PTRACE_EVENT_FORK

Event that stops before a return from fork or clone.

PTRACE_EVENT_VFORK

Event that stops before a return from vfork or clone.

PTRACE_EVENT_CLONE

Event that stops before a return from clone.

PTRACE_EVENT_EXEC

Event that stops before a return from execve.

PTRACE_EVENT_VFORK_DONE

Event for a return from vfork.

PTRACE_EVENT_EXIT

Event for a stop before an exit. Unlike the waitpid Exit status program. registers can still be examined

PTRACE_EVENT_SECCOMP

Stop triggered by a seccomp rule on a tracee.

PTRACE_EVENT_STOP

Stop triggered by the INTERRUPT syscall, or a group stop, or when a new child is attached.

Trait Implementations

impl Clone for Event

fn clone(&self) -> Event

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Event

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

Formats the value using the given formatter.

impl Hash for Event

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

Feeds this value into the given Hasher.

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

Feeds a slice of this type into the given Hasher.

impl Ord for Event

fn cmp(&self, other: &Event) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Selfwhere
    Self: PartialOrd<Self>,

Restrict a value to a certain interval.

impl PartialEq<Event> for Event

fn eq(&self, other: &Event) -> 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.

impl PartialOrd<Event> for Event

fn partial_cmp(&self, other: &Event) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

This method tests less than (for self and other) and is used by the < operator.

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

This method tests less than or equal to (for self and other) and is used by the <= operator.

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

This method tests greater than (for self and other) and is used by the > operator.

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

This method tests greater than or equal to (for self and other) and is used by the >= operator.
