Struct sunrise_kernel::i386::structures::idt::EntryOptions

pub struct EntryOptions(pub u8);

Represents the options field of an IDT entry.

Implementations

impl EntryOptions

fn gate_type(&self) -> GateType

Type of the interrupt handler. Its value determines the mechanism used to trigger the handler.

fn privilege_level(&self) -> PrivilegeLevel

fn is_present(&self) -> bool

fn set_is_present(&mut self, value: bool)

impl EntryOptions

fn minimal() -> Self

Creates a minimal options field with all the must-be-one bits set.

fn set_gate_type(&mut self, gate_type: GateType) -> &mut Self

Set the kind of gate this IdtEntry represents.

pub fn set_privilege_level(&mut self, privlvl: PrivilegeLevel) -> &mut Self

Set the required privilege level (DPL) for invoking the handler. If CPL < DPL, a general protection fault occurs.

pub fn set_present_interrupt(&mut self, present: bool) -> &mut Self

Set or reset the preset bit.

pub fn set_present_task(&mut self, present: bool) -> &mut Self

Set or reset the preset bit.

pub fn disable_interrupts(&mut self, disable: bool) -> &mut Self

Let the CPU disable hardware interrupts when the handler is invoked. By default, interrupts are disabled on handler invocation.

Trait Implementations

impl<T> BitRange<T> for EntryOptions where
    u8: BitRange<T>, 

fn bit_range(&self, msb: usize, lsb: usize) -> T

Get a range of bits.

fn set_bit_range(&mut self, msb: usize, lsb: usize, value: T)

Set a range of bits.

impl Clone for EntryOptions

fn clone(&self) -> EntryOptions

Returns a copy of the value.

Performs copy-assignment from source.

impl Copy for EntryOptions

impl Debug for EntryOptions

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

Formats the value using the given formatter.
