Struct MpolFlags 

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

Optional mode flags for set_mempolicy(2).

OR’d into the mode argument. See MPOL_F_* in include/uapi/linux/mempolicy.h.

Implementations

impl MpolFlags

pub const NONE: Self

No flags.

pub const STATIC_NODES: Self

MPOL_F_STATIC_NODES (1 << 15): nodemask is absolute, not remapped when the task’s cpuset changes.

pub const RELATIVE_NODES: Self

MPOL_F_RELATIVE_NODES (1 << 14): nodemask is relative to the task’s current cpuset.

pub const NUMA_BALANCING: Self

MPOL_F_NUMA_BALANCING (1 << 13): enable NUMA balancing optimization for this policy.

pub const fn union(self, other: Self) -> Self

Combine two flag sets.

pub const fn bits(self) -> u32

Raw flag bits for passing to the syscall.

pub const fn contains(self, other: Self) -> bool

Whether every bit in other is set in self.

Set-theoretic, not syntactic: contains(NONE) returns true for any self (vacuous truth — the empty set is a subset of everything). Callers who want “has a non-empty intersection with other” must compare self.bits() & other.bits() != 0 explicitly; using contains for that query silently returns true when the operand is NONE regardless of self.

Trait Implementations

impl BitOr for MpolFlags

fn bitor(self, rhs: Self) -> Self

Delegates to MpolFlags::union so the bitwise-OR logic lives in one place. union is const fn (usable in const contexts like const initializers); BitOr::bitor cannot currently be const on stable, so keeping both entry points is necessary, but they must never diverge.

type Output = MpolFlags

The resulting type after applying the | operator.

impl Clone for MpolFlags

fn clone(&self) -> MpolFlags

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MpolFlags

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

Formats the value using the given formatter.

impl Default for MpolFlags

fn default() -> MpolFlags

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for MpolFlags

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for MpolFlags

fn eq(&self, other: &MpolFlags) -> 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.

impl Serialize for MpolFlags

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Copy for MpolFlags
