Struct MAPIOutParam 

pub struct MAPIOutParam<T>(/* private fields */)
where
    T: Sized;

Hold an out-pointer for MAPI APIs which perform their own buffer allocations. This version does not perform any validation of the buffer size, so the typed accessors are inherently unsafe.

Implementations

impl<T> MAPIOutParam<T>

where T: Sized,

pub fn as_mut_ptr(&mut self) -> *mut *mut T

Get a *mut *mut T suitable for use with a MAPI API that fills in an out-pointer with a newly allocated buffer.

pub unsafe fn as_mut(&mut self) -> Option<&mut T>

Access a single element of type T.

Safety

This version does not perform any validation of the buffer size, so the typed accessors are inherently unsafe. The only thing it handles is a null check.

pub unsafe fn as_mut_slice(&mut self, count: usize) -> Option<&mut [T]>

Access a slice with count elements of type T.

Safety

This version does not perform any validation of the buffer size, so the typed accessors are inherently unsafe. The only thing it handles is a null check.

Trait Implementations

impl<T> Default for MAPIOutParam<T>

where T: Sized,

fn default() -> Self

Returns the “default value” for a type.

impl<T> Drop for MAPIOutParam<T>

where T: Sized,

fn drop(&mut self)

Executes the destructor for this type.

fn pin_drop(self: Pin<&mut Self>)

🔬This is a nightly-only experimental API. (pin_ergonomics)

Execute the destructor for this type, but different to Drop::drop, it requires self to be pinned.
