Enum SyscallState

#[repr(C)]
pub enum SyscallState {
    Executing,
    Suspend(u64),
    Timeout,
    Callback,
}

Enums used to describe syscall state

Variants

Executing

执行中

Suspend(u64)

被挂起到指定时间后继续执行，参数为时间戳

Timeout

到指定时间戳后回来，期间系统调用可能没执行完毕 对于sleep系列，这个状态表示正常完成

Callback

系统调用回调成功

Trait Implementations

impl Clone for SyscallState

fn clone(&self) -> SyscallState

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for SyscallState

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

Formats the value using the given formatter.

impl Display for SyscallState

where SyscallState: Debug,

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

Formats the value using the given formatter.

impl PartialEq for SyscallState

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