Struct PageBuf 

pub struct PageBuf<T> { /* private fields */ }

A buffer backed by a VMO mapped into the root VMAR.

Optionally maps the buffer into a second VMAR as read-only to allow pinning memory in advance of support for partial VMAR profiles or a similar feature.

Implementations

impl<T> PageBuf<T>

pub fn new(capacity: usize) -> Result<Self, Status>

Create a new PageBuf in the calling process’ root VMAR.

pub fn new_with_extra_vmar( capacity: usize, extra_vmar: Arc<Vmar>, ) -> Result<Self, Status>

Create a new PageBuf in the calling process’ root VMAR and also map the VMO into the provided “extra” VMAR. If the extra VMAR has a memory profile this will

pub fn set_name(&self, name: &Name)

Set the name of the buffer’s VMO.

pub fn len(&self) -> usize

pub fn len_bytes(&self) -> usize

pub fn as_mut(&mut self) -> &mut [MaybeUninit<T>]

Return a mutable reference to the underlying memory.
