Struct Session 

pub struct Session {
    pub leader: pid_t,
    pub mutable_state: LockDepRwLock<SessionMutableState, SessionMutableStateLock>,
}

A session is a collection of ProcessGroup objects that are related to each other. Each session has a session ID (sid), which is a unique identifier for the session.

The session leader is the first ProcessGroup in a session. It is responsible for managing the session, including sending signals to all processes in the session and controlling the foreground and background process groups.

When a ProcessGroup is created, it is automatically added to the session of its parent. See setsid(2) for information about creating sessions.

A session can be destroyed when the session leader exits or when all process groups in the session are destroyed.

Fields

leader: pid_t

The leader of the session

mutable_state: LockDepRwLock<SessionMutableState, SessionMutableStateLock>

The mutable state of the Session.

Implementations

impl Session

pub fn new(leader: pid_t) -> Arc<Session>

pub fn disassociate_controlling_terminal<L>(&self, locked: &mut Locked<L>)

where L: LockBefore<ProcessGroupState>,

Disassociates the controlling terminal from the session.

pub fn read(&self) -> impl Deref<Target = SessionMutableState>

pub fn write(&self) -> impl DerefMut<Target = SessionMutableState>

Trait Implementations

impl Debug for Session

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

Formats the value using the given formatter.

impl PartialEq for Session

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