Struct x86_64::structures::gdt::SegmentSelector

#[repr(transparent)]
pub struct SegmentSelector(pub 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”

Implementations

impl SegmentSelector

pub const fn new(index: u16, rpl: PrivilegeLevel) -> SegmentSelector

Creates a new SegmentSelector

Arguments

• index: index in GDT or LDT array (not the offset)
• rpl: the requested privilege level

pub fn index(self) -> u16

Returns the GDT index.

pub fn rpl(self) -> PrivilegeLevel

Returns the requested privilege level.

pub fn set_rpl(&mut self, rpl: PrivilegeLevel)

Set the privilege level for this Segment selector.
