Enum CpuLocalError 

pub enum CpuLocalError {
    AreaNotInstalled,
    InvalidAreaBase {
        base: usize,
    },
    AddressOverflow,
    AreaIdentityMismatch,
    UnsupportedHostLevel {
        level: usize,
    },
    CurrentContextMismatch,
}

Failure to construct, install, or observe CPU-local state.

Variants

AreaNotInstalled

No runtime CPU area has been installed in the architecture register.

InvalidAreaBase

A runtime CPU-area address is null or does not meet prefix alignment.

Fields

base: usize

Rejected runtime address.

AddressOverflow

Address arithmetic for the fixed CPU-area prefix overflowed.

AreaIdentityMismatch

The immutable area header does not describe its actual address.

UnsupportedHostLevel

The kernel is running at an exception level unsupported by this backend.

Fields

level: usize

Architecture-specific live exception level.

CurrentContextMismatch

The selected current-context source does not identify a valid context.

Trait Implementations

impl Clone for CpuLocalError

fn clone(&self) -> CpuLocalError

Returns a duplicate of the value.

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

impl Eq for CpuLocalError

impl Error for CpuLocalError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

impl From<CpuLocalError> for ContextSwitchError

fn from(source: CpuLocalError) -> Self

Converts to this type from the input type.

impl PartialEq for CpuLocalError

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

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
