Struct winsafe::guard::CoLockObjectExternalGuard

source · 
pub struct CoLockObjectExternalGuard<'a, T>
where
    T: ole_IUnknown,
{ /* private fields */ }
Available on crate features kernel and ole only.
Expand description

RAII implementation which automatically calls CoLockObjectExternal to unlock the COM pointer.

Implementations§

source§

impl<'a, T> CoLockObjectExternalGuard<'a, T>
where T: ole_IUnknown,

source

pub const unsafe fn new(com_obj: &'a T) -> Self

Constructs the guard by keeping the reference to the COM pointer.

§Safety

Be sure the COM pointer has been locked with a previous call to CoLockObjectExternal.
