Struct libseccomp::ScmpNotifReq

#[non_exhaustive]
pub struct ScmpNotifReq {
    pub id: u64,
    pub pid: u32,
    pub flags: u32,
    pub data: ScmpNotifData,
}

Represents a userspace notification request.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

id: u64

Notification ID

pid: u32

Process that triggered the notification event

flags: u32

Filter flags (see seccomp(2))

data: ScmpNotifData

System call context that triggered the notification

Implementations

impl ScmpNotifReq

pub fn receive(fd: ScmpFd) -> Result<Self, SeccompError>

Retrieves a userspace notification from a filter whose crate::ScmpAction::Notify action has triggered.

The caller is expected to process the notification and return a response via ScmpNotifResp::respond(). Each invocation of this function returns one notification. As multiple notifications may be pending at any time, this function is normally called within a polling loop.

This function returns a userspace notification request.

This function corresponds to seccomp_notify_receive.

Arguments

• fd - A file descriptor for the userspace notification

Errors

If an issue is encountered getting a notification request, an error will be returned.

Trait Implementations

impl Clone for ScmpNotifReq

fn clone(&self) -> ScmpNotifReq

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ScmpNotifReq

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

Formats the value using the given formatter.

impl Hash for ScmpNotifReq

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 PartialEq<ScmpNotifReq> for ScmpNotifReq

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