Struct MAPIBuffer

pub struct MAPIBuffer<'a, T>(/* private fields */)
where
    T: Sized;

Wrapper type for an allocation in MAPIUninit which has been fully initialized.

Implementations

impl<'a, T> MAPIBuffer<'a, T>

pub fn chain<P>( &self, count: usize, ) -> Result<MAPIUninit<'a, P>, MAPIAllocError>

Create a new allocation with enough room for count elements of type P with a call to sys::MAPIAllocateMore. The result is a separate allocation that is not freed until self is dropped at the beginning of the chain.

You may call MAPIBuffer::chain on the result as well, they will both share a root allocation created with MAPIUninit::new.

pub fn as_mut(&mut self) -> Result<&mut T, MAPIAllocError>

Access a single element of type T once it has been initialized with MAPIUninit::assume_init.
