Struct NumaNode 

pub struct NumaNode(/* private fields */);

A NUMA node number, as Windows numbers them.

A newtype rather than a bare u32 because the two u32s in this area mean different things and are trivially swapped at a call site: a node number and a count of nodes are both small integers, and highest_numa_node returns the former while reading like the latter.

Node numbers are not an index. Windows does not promise they run 0..n, so a caller deriving a node from a position in some list is making an assumption the platform never offered – see windows-placement-probe, where a positional index reaching VirtualAllocExNuma was a real defect and is called out at the site that fixed it.

Implementations

impl NumaNode

pub const fn new(node: u32) -> Self

Wrap a raw node number.

Not validated against the machine: VirtualAllocExNuma is where an impossible node is rejected, and validating here would mean a second, weaker opinion about what exists. See NumaBuffer::new for what the platform actually does with an out-of-range node, which is not what its documentation says.

pub const fn get(self) -> u32

The raw node number, for handing to a Win32 call.
