Enum WakeMechanism 

pub enum WakeMechanism {
    Pipe,
    Futex,
}

Wake mechanism between stages of a WorkType::WakeChain.

Carried as a typed enum rather than a bool so call sites name the choice explicitly (Pipe / Futex) instead of a bare sync: true / sync: false. The serde wire format is "pipe" / "futex" (snake_case).

Variants

Pipe

Anon-pipe ring (depth pipes per chain). Wakes carry WF_SYNC via wake_up_interruptible_sync_poll, biasing scheduler placement against migration. Tests the SCX_WAKE_SYNC path that scx variants must respect. The default — see WakeChain in WorkType for the kernel call-chain citations.

Futex

Single shared futex word per chain. The active stage advances the word and FUTEX_WAKEs; the stage whose pos matches runs, others re-park. No WF_SYNC.

Trait Implementations

impl Clone for WakeMechanism

fn clone(&self) -> WakeMechanism

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for WakeMechanism

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

Formats the value using the given formatter.

impl Default for WakeMechanism

fn default() -> WakeMechanism

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for WakeMechanism

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for WakeMechanism

fn eq(&self, other: &WakeMechanism) -> 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 WakeMechanism

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 WakeMechanism
