Struct NumaNode 

Source 
pub struct NumaNode(/* private fields */);
Expand description

Non Uniform Memory Access (NUMA) node identifier.

Implementations§

Source§

impl NumaNode

Source

pub fn new(node: i32) -> Result<Self>

Create a new NUMA node identifier (non-negative integer).

Returns EINVAL if a negative id or an id exceeding [bindings::MAX_NUMNODES] is specified.

Source

pub fn id(&self) -> i32

Returns the raw NUMA node identifier as an i32.

Source§

impl NumaNode

Specify necessary constant to pass the information to Allocator that the caller doesn’t care about the NUMA node to allocate memory from.

Source

pub const NO_NODE: NumaNode

No node preference.
