Struct rstubs::arch::gdt::SegmentSelector

#[repr(transparent)]
pub struct SegmentSelector(u16);

Specifies which element to load into a segment from descriptor tables (i.e., is a index to LDT or GDT table with some additional flags).

See Intel 3a, Section 3.4.2 “Segment Selectors”

Trait Implementations

impl Clone for SegmentSelector

fn clone(&self) -> SegmentSelector

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for SegmentSelector

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

Formats the value using the given formatter.

impl Default for SegmentSelector

fn default() -> Self

Returns the “default value” for a type.

impl From<SegmentSelector> for u16

fn from(v: SegmentSelector) -> u16

Converts to this type from the input type.

impl From<u16> for SegmentSelector

fn from(v: u16) -> Self

Converts to this type from the input type.

impl PartialEq for SegmentSelector

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