Enum sunrise_kernel::process::ThreadState

#[repr(usize)]pub enum ThreadState {
    Paused,
    Running,
    TerminationPending,
    Scheduled,
}

The state of a thread.

• Paused: not in the scheduled queue, waiting for an event
• Running: currently on the CPU
• TerminationPending: dying, will be unscheduled and dropped at syscall boundary
• Scheduled: scheduled to be running

Since SMP is not supported, there is only one Running thread.

Variants

Paused

Not in the scheduled queue, waiting for an event.

Running

Currently on the CPU.

TerminationPending

Dying, will be unscheduled and dropped at syscall boundary.

Scheduled

Scheduled to be running.

Implementations

impl ThreadState

fn from_primitive(v: usize) -> ThreadState

ThreadState is stored in the ThreadStruct as an AtomicUsize. This function casts it back to the enum.

Trait Implementations

impl Clone for ThreadState

fn clone(&self) -> ThreadState

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Copy for ThreadState

impl Debug for ThreadState

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

Formats the value using the given formatter.

impl Eq for ThreadState

impl PartialEq<ThreadState> for ThreadState

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

This method tests for self and other values to be equal, and is used by ==.

#[must_use]fn ne(&self, other: &Rhs) -> bool

This method tests for !=.
