Struct SelectorErrorCode

pub struct SelectorErrorCode { /* private fields */ }

Describes an error code referencing a segment selector.

Implementations

impl SelectorErrorCode

pub const fn new(value: u64) -> Option<Self>

Create a SelectorErrorCode. Returns None is any of the reserved bits (16-64) are set.

pub const fn new_truncate(value: u64) -> Self

Create a new SelectorErrorCode dropping any reserved bits (16-64).

pub fn external(&self) -> bool

If true, indicates that the exception occurred during delivery of an event external to the program, such as an interrupt or an earlier exception.

pub fn descriptor_table(&self) -> DescriptorTable

The descriptor table this error code refers to.

pub fn index(&self) -> u64

The index of the selector which caused the error.

pub fn is_null(&self) -> bool

If true, the #SS or #GP has returned zero as opposed to a SelectorErrorCode.

Trait Implementations

impl Clone for SelectorErrorCode

fn clone(&self) -> SelectorErrorCode

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for SelectorErrorCode

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

Formats the value using the given formatter.

impl Hash for SelectorErrorCode

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for SelectorErrorCode

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