Struct NodeMask 

pub struct NodeMask { /* private fields */ }

A set of NUMA node IDs.

NodeMask represents a collection of NUMA nodes, used for memory policies like Bind and Interleave.

Implementations

impl NodeMask

pub const MAX_NODES: usize = 64

Maximum number of nodes supported.

pub const fn new() -> Self

Create an empty node mask.

pub fn single(node: NodeId) -> Self

Create a node mask containing a single node.

pub fn add(&mut self, node: NodeId)

Add a node to the mask.

Panics

Panics if node.0 >= MAX_NODES.

pub fn remove(&mut self, node: NodeId)

Remove a node from the mask.

pub fn contains(&self, node: NodeId) -> bool

Check if a node is in the mask.

pub fn is_empty(&self) -> bool

Check if the mask is empty.

pub fn count(&self) -> usize

Count the number of nodes in the mask.

pub fn iter(&self) -> impl Iterator<Item = NodeId> + '_

Iterate over the nodes in the mask.

pub fn first(&self) -> Option<NodeId>

Get the first node in the mask, if any.

pub fn as_raw(&self) -> u64

Get the raw bitmap for FFI.

pub const fn from_raw(bits: u64) -> Self

Create from a raw bitmap.

Trait Implementations

impl Clone for NodeMask

fn clone(&self) -> NodeMask

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for NodeMask

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for NodeMask

fn default() -> Self

Returns the “default value” for a type.

impl Display for NodeMask

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl From<&[NodeId]> for NodeMask

fn from(nodes: &[NodeId]) -> Self

Converts to this type from the input type.

impl<const N: usize> From<[NodeId; N]> for NodeMask

fn from(nodes: [NodeId; N]) -> Self

Converts to this type from the input type.

impl From<NodeId> for NodeMask

fn from(node: NodeId) -> Self

Converts to this type from the input type.

impl FromIterator<NodeId> for NodeMask

fn from_iter<I: IntoIterator<Item = NodeId>>(iter: I) -> Self

Creates a value from an iterator.

impl PartialEq for NodeMask

fn eq(&self, other: &NodeMask) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
