Enum kernel::process::StoppedExecutingReason

pub enum StoppedExecutingReason {
    NoWorkLeft,
    StoppedFaulted,
    Stopped,
    TimesliceExpired,
    KernelPreemption,
}

Enum used to inform scheduler why a process stopped executing (aka why do_process() returned).

This is publicly exported to allow for schedulers implemented outside of the kernel crate.

Variants

NoWorkLeft

The process returned because it is no longer ready to run.

StoppedFaulted

The process faulted, and the board restart policy was configured such that it was not restarted and there was not a kernel panic.

Stopped

The kernel stopped the process.

TimesliceExpired

The process was preempted because its timeslice expired.

KernelPreemption

The process returned because it was preempted by the kernel. This can mean that kernel work became ready (most likely because an interrupt fired and the kernel thread needs to execute the bottom half of the interrupt), or because the scheduler no longer wants to execute that process.

Trait Implementations

impl Eq for StoppedExecutingReason

#[doc(hidden)] fn assert_receiver_is_total_eq(&self)

impl PartialEq for StoppedExecutingReason

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