GuestMemoryAbi

Struct GuestMemoryAbi

#[repr(C)]pub struct GuestMemoryAbi {
    pub pages: *const GuestPageAbi,
    pub page_count: usize,
    pub page_size: usize,
    pub translations: [GuestTranslationAbi; 16],
    pub dirty_pages: *mut usize,
    pub dirty_count: usize,
    pub dirty_bitmap: *mut u64,
}

Expand description

Exposes only stable pointers and lengths because generated code cannot use Rust containers.

Fields§

§pages: *const GuestPageAbi

Points to the sorted page descriptions used by generated binary search.

§page_count: usize

Limits generated searches to valid entries in pages.

§page_size: usize

Gives the page size that defines guest page offsets.

§translations: [GuestTranslationAbi; 16]

Keeps recent translations so common accesses do not need binary search.

§dirty_pages: *mut usize

Points to page indices changed since the current snapshot baseline.

§dirty_count: usize

Gives the valid prefix length of dirty_pages.

§dirty_bitmap: *mut u64

Points to one bit per page so each dirty page enters the list once.
