Struct x86_64::structures::idt::Entry

#[repr(C)]
pub struct Entry<F> { /* private fields */ }

An Interrupt Descriptor Table entry.

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

Implementations

impl<F> Entry<F>

pub const fn missing() -> Self

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

pub unsafe fn set_handler_addr(&mut self, addr: VirtAddr) -> &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.

Safety

The caller must ensure that addr is the address of a valid interrupt handler function, and the signature of such a function is correct for the entry type.

pub fn handler_addr(&self) -> VirtAddr

Returns the virtual address of this IDT entry’s handler function.

impl Entry<HandlerFunc>

pub fn set_handler_fn(&mut self, handler: HandlerFunc) -> &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.

This method is only usable with the abi_x86_interrupt feature enabled. Without it, the unsafe Entry::set_handler_addr method has to be used instead.

impl Entry<HandlerFuncWithErrCode>

pub fn set_handler_fn( &mut self, handler: HandlerFuncWithErrCode ) -> &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.

This method is only usable with the abi_x86_interrupt feature enabled. Without it, the unsafe Entry::set_handler_addr method has to be used instead.

impl Entry<PageFaultHandlerFunc>

pub fn set_handler_fn( &mut self, handler: PageFaultHandlerFunc ) -> &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.

This method is only usable with the abi_x86_interrupt feature enabled. Without it, the unsafe Entry::set_handler_addr method has to be used instead.

impl Entry<DivergingHandlerFunc>

pub fn set_handler_fn( &mut self, handler: DivergingHandlerFunc ) -> &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.

This method is only usable with the abi_x86_interrupt feature enabled. Without it, the unsafe Entry::set_handler_addr method has to be used instead.

impl Entry<DivergingHandlerFuncWithErrCode>

pub fn set_handler_fn( &mut self, handler: DivergingHandlerFuncWithErrCode ) -> &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.

This method is only usable with the abi_x86_interrupt feature enabled. Without it, the unsafe Entry::set_handler_addr method has to be used instead.

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<T> Debug for Entry<T>

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

Formats the value using the given formatter.

impl<T> PartialEq for Entry<T>

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