Struct kalloc::guard::AllocGuard[−][src]

pub struct AllocGuard { /* fields omitted */ }
Expand description

Smart pointer guard.

Implementations

impl AllocGuard[src]

pub fn new(layout: Layout) -> Result<Self, AllocError>[src]

Create a new smart pointer.

pub fn ptr(&self) -> NonNull<u8>[src]

Get the pointer inside.

pub fn as_slice(&self) -> &[u8]ⓘ

Notable traits for &'_ [u8]

impl<'_> Read for &'_ [u8]impl<'_> Write for &'_ mut [u8]
[src]

Extract the slice.

pub fn as_mut_slice(&self) -> &mut [u8]ⓘ

Notable traits for &'_ [u8]

impl<'_> Read for &'_ [u8]impl<'_> Write for &'_ mut [u8]
[src]

Extract the mutable slice.

pub fn consume(self)[src]

Drop and don’t deallocate the pointer.

Often called when the ownership of the pointer is transfered.

pub unsafe fn from_ptr(ptr: NonNull<u8>, layout: Layout) -> Self[src]

Create a new smart pointer from raw pointer.

SAFETY: You must guarantee that

  • ptr and layout are valid.
  • [consume] is called before anyone uses ptr.
