Enum VmIoMemView 

pub enum VmIoMemView<'a> {
    WriteView(MemView),
    ReadView(&'a MemView),
}

The memory view used for VM I/O operations.

The readers can think of this as a wrapped permission tokens for operating with a certain memory view (see MemView) “owned” by the VmIoOwner that they are created from, which are used for allowing callers to use VmReader and VmWriter to perform VM I/O operations.

For writers the memory permission must be exclusive so this enum contains an owned MemView for the write view; for readers the memory permission can be shared so this enum contains a reference to a MemView for the read view (which can be disabled optionally in VmSpaceOwner).

⚠️ WARNING: We do not recommend using this enum directly.

Variants

WriteView(MemView)

An owned memory for writing.

ReadView(&'a MemView)

A shared memory for reading.
