Struct rstubs::arch::int::idt::Entry

#[repr(C)]
pub struct Entry<F> {
    pointer_low: u16,
    code_segment: SegmentSelector,
    options: EntryOptions,
    pointer_middle: u16,
    phantom: PhantomData<F>,
}

An Interrupt Descriptor Table entry.

The generic parameter can either be HandlerFunc or HandlerFuncWithErrCode, depending on the interrupt vector.

Fields

pointer_low: u16

code_segment: SegmentSelector

options: EntryOptions

pointer_middle: u16

phantom: PhantomData<F>

Implementations

impl<F> Entry<F>

pub fn missing() -> Self

Creates a non-present IDT entry (but sets the must-be-one bits).

fn set_handler_addr(&mut self, addr: u32) -> &mut EntryOptions

Set the handler address for the IDT entry and sets the present bit.

For the code selector field, this function uses the code segment selector currently active in the CPU.

The function returns a mutable reference to the entry’s options that allows further customization.

impl Entry<unsafe extern "x86-interrupt" fn(_: InterruptStack)>

pub fn set_handler_fn( &mut self, handler: unsafe extern "x86-interrupt" fn(_: InterruptStack) ) -> &mut EntryOptions

Set the handler function for the IDT entry and sets the present bit.

For the code selector field, this function uses the code segment selector currently active in the CPU.

The function returns a mutable reference to the entry’s options that allows further customization.

impl Entry<unsafe extern "x86-interrupt" fn(_: InterruptStack, error_code: u32)>

pub fn set_handler_fn( &mut self, handler: unsafe extern "x86-interrupt" fn(_: InterruptStack, error_code: u32) ) -> &mut EntryOptions

Set the handler function for the IDT entry and sets the present bit.

For the code selector field, this function uses the code segment selector currently active in the CPU.

The function returns a mutable reference to the entry’s options that allows further customization.

impl Entry<unsafe extern "x86-interrupt" fn(_: InterruptStack, error_code: PageFaultError)>

pub fn set_handler_fn( &mut self, handler: unsafe extern "x86-interrupt" fn(_: InterruptStack, error_code: PageFaultError) ) -> &mut EntryOptions

Set the handler function for the IDT entry and sets the present bit.

For the code selector field, this function uses the code segment selector currently active in the CPU.

The function returns a mutable reference to the entry’s options that allows further customization.

impl Entry<unsafe extern "x86-interrupt" fn(_: InterruptStack) -> !>

pub fn set_handler_fn( &mut self, handler: unsafe extern "x86-interrupt" fn(_: InterruptStack) -> ! ) -> &mut EntryOptions

Set the handler function for the IDT entry and sets the present bit.

For the code selector field, this function uses the code segment selector currently active in the CPU.

The function returns a mutable reference to the entry’s options that allows further customization.

impl Entry<unsafe extern "x86-interrupt" fn(_: InterruptStack, error_code: u32) -> !>

pub fn set_handler_fn( &mut self, handler: unsafe extern "x86-interrupt" fn(_: InterruptStack, error_code: u32) -> ! ) -> &mut EntryOptions

Set the handler function for the IDT entry and sets the present bit.

For the code selector field, this function uses the code segment selector currently active in the CPU.

The function returns a mutable reference to the entry’s options that allows further customization.

Trait Implementations

impl<F: Clone> Clone for Entry<F>

fn clone(&self) -> Entry<F>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<F: Debug> Debug for Entry<F>

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

Formats the value using the given formatter.

impl<F: PartialEq> PartialEq for Entry<F>

fn eq(&self, other: &Entry<F>) -> 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.
