Trait FromRawHandle
trait FromRawHandle
Constructs I/O objects from raw handles.
Required Methods
unsafe fn from_raw_handle(handle: RawHandle) -> SelfConstructs a new I/O object from the specified raw handle.
This function is typically used to consume ownership of the handle given, passing responsibility for closing the handle to the returned object. When used in this way, the returned object will take responsibility for closing it when the object goes out of scope.
However, consuming ownership is not strictly required. Use a
From<OwnedHandle>::fromimplementation for an API which strictly consumes ownership.Safety
The
handlepassed in must:- be an owned handle; in particular, it must be open.
- be a handle for a resource that may be freed via
CloseHandle(as opposed toRegCloseKeyor other close functions).
Note that the handle may have the value
INVALID_HANDLE_VALUE(-1), which is sometimes a valid handle value. See here for the full story.
