Struct TaskPersistentInfoState 

pub struct TaskPersistentInfoState {
    pub tid: Pid,
    pub pid: Pid,
    /* private fields */
}

The information of the task that needs to be available to the ThreadGroup while computing which process a wait can target. It is necessary to shared this data with the ThreadGroup so that it is available while the task is being dropped and so is not accessible from a weak pointer.

Fields

tid: Pid

Immutable information about the task

pid: Pid

Implementations

impl TaskPersistentInfoState

pub fn command_guard(&self) -> LockDepGuard<'_, TaskCommand>

pub fn real_creds(&self) -> RcuReadGuard<Credentials>

Snapshots the credentials, returning a short-lived RCU-guarded reference.

pub fn clone_creds(&self) -> Arc<Credentials>

Snapshots the credentials, returning a new reference. Use this if you need to stash the credentials somewhere.

pub fn lock_creds(&self) -> CredentialsReadGuard<'_>

Returns a read lock on the credentials. This is appropriate if you need to guarantee that the Task’s credentials will not change during a security-sensitive operation.

Trait Implementations

impl Ord for TaskPersistentInfoState

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

This method returns an Ordering between self and other.

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

where Self: Sized,

Compares and returns the maximum of two values.

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

where Self: Sized,
