Struct Pages

pub struct Pages<'t>(/* private fields */);

Memory pages

Implementations

impl<'t> Pages<'t>

pub fn granularity() -> usize

pub fn align(offset: usize) -> usize

pub unsafe fn from_slice(slice: NonNull<[u8]>) -> Pages<'t>

Create Pages from non‐null raw u8 slice

Safety

slice must be aligned to and have a size that is a multiple of the page size.

pub unsafe fn from_raw_parts(ptr: NonNull<u8>, size: usize) -> Pages<'t>

Create Pages from non‐null u8 pointer and length

Safety

ptr must be aligned to a multiple of the page size and size must be a multiple of the page size.

pub unsafe fn from_ptr<T>(ptr: *mut T, size: usize) -> Pages<'t>

Create Pages from pointer and length

Safety

ptr must be non‐null and aligned to a multiple of the page size and size must be a multiple of the page size.

Panics

May panic if ptr is null or if ptr or size are not properly aligned.
