Struct kernel::AppSlice

pub struct AppSlice<L, T> {
    ptr: AppPtr<L, T>,
    len: usize,
}

Buffer of memory shared from an app to the kernel.

This is the type created after an app calls the allow syscall.

Fields

ptr: AppPtr<L, T>

len: usize

Methods

impl<L, T> AppSlice<L, T>

pub(crate) fn new(ptr: *mut T, len: usize, appid: AppId) -> AppSlice<L, T>

pub fn len(&self) -> usize

Number of bytes in the AppSlice.

pub fn ptr(&self) -> *const T

Get the raw pointer to the buffer. This will be a pointer inside of the app's memory region.

pub(crate) unsafe fn expose_to(&self, appid: AppId) -> bool

Provide access to one app's AppSlice to another app. This is used for IPC.

pub fn iter(&self) -> Iter<T>

pub fn iter_mut(&mut self) -> IterMut<T>

pub fn chunks(&self, size: usize) -> Chunks<T>

pub fn chunks_mut(&mut self, size: usize) -> ChunksMut<T>
