Enum kernel::syscall::ContextSwitchReason

pub enum ContextSwitchReason {
    SyscallFired {
        syscall: Syscall,
    },
    Fault,
    Interrupted,
}

ContentSwitchReason specifies why the process stopped executing and execution returned to the kernel.

Variants

SyscallFired

Fields

syscall: Syscall

Process called a syscall. Also returns the syscall and relevant values.

Fault

Process triggered the hardfault handler. The implementation should still save registers in the event that the Platform can handle the fault and allow the app to continue running. For more details on this see Platform::process_fault_hook().

Interrupted

Process interrupted (e.g. by a hardware event)

Trait Implementations

impl Clone for ContextSwitchReason

fn clone(&self) -> ContextSwitchReason

Returns a copy of the value.

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

Performs copy-assignment from source.

impl PartialEq for ContextSwitchReason

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