Module x86_64::structures::idt

Provides types for the Interrupt Descriptor Table and its entries.

For the builds without the abi_x86_interrupt feature

The following types are opaque and non-constructable instead of function pointers.

• DivergingHandlerFunc
• DivergingHandlerFuncWithErrCode
• HandlerFunc
• HandlerFuncWithErrCode
• PageFaultHandlerFunc

These types are defined for the compatibility with the Nightly Rust build.

Structs

• Entry
  An Interrupt Descriptor Table entry.
• EntryOptions
  Represents the 4 non-offset bytes of an IDT entry.
• InterruptDescriptorTable
  An Interrupt Descriptor Table with 256 entries.
• InterruptStackFrame
  Wrapper type for the interrupt stack frame pushed by the CPU.
• InterruptStackFrameValue
  Represents the interrupt stack frame pushed by the CPU on interrupt or exception entry.
• PageFaultErrorCode
  Describes an page fault error code.
• SelectorErrorCode
  Describes an error code referencing a segment selector.

Enums

• DescriptorTable
  The possible descriptor table values.
• ExceptionVector
  This structure defines the CPU-internal exception vector numbers.

Traits

• HandlerFuncType
  A common trait for all handler functions usable in Entry.

Type Aliases

• DivergingHandlerFuncabi_x86_interrupt
  A handler function that must not return, e.g. for a machine check exception.
• DivergingHandlerFuncWithErrCodeabi_x86_interrupt
  A handler function with an error code that must not return, e.g. for a double fault exception.
• GeneralHandlerFunc
  A general handler function for an interrupt or an exception with the interrupt/exceptions’s index and an optional error code.
• HandlerFuncabi_x86_interrupt
  A handler function for an interrupt or an exception without error code.
• HandlerFuncWithErrCodeabi_x86_interrupt
  A handler function for an exception that pushes an error code.
• PageFaultHandlerFuncabi_x86_interrupt
  A page fault handler function that pushes a page fault error code.
