Struct x86::segmentation::DescriptorBuilder

pub struct DescriptorBuilder { /* private fields */ }

Makes building descriptors easier (hopefully).

Implementations

impl DescriptorBuilder

pub fn limit_granularity_4kb(self) -> DescriptorBuilder

The segment limit is interpreted in 4-KByte units if this is set.

pub fn present(self) -> DescriptorBuilder

Indicates whether the segment is present in memory (set) or not present (clear).

pub fn dpl(self, dpl: Ring) -> DescriptorBuilder

Specifies the privilege level of the segment.

pub fn avl(self) -> DescriptorBuilder

Toggle the AVL bit.

pub fn db(self) -> DescriptorBuilder

Set default operation size (false for 16bit segment, true for 32bit segments).

pub fn l(self) -> DescriptorBuilder

Set L bit if this descriptor is a 64-bit code segment. In IA-32e mode, bit 21 of the second doubleword of the segment descriptor indicates whether a code segment contains native 64-bit code. A value of 1 indicates instructions in this code segment are executed in 64-bit mode.

pub fn ist(self, index: u8) -> DescriptorBuilder

Set a the interrupt stack table index (only if this ends up being a 64-bit interrupt descriptor).
