Enum MemHedgeState 

#[repr(u8)]
pub enum MemHedgeState {
    Idle = 0,
    Armed = 1,
    Claimed = 2,
}

🫗 🧵 ⚛️ Lifecycle state of a hedged read request.

---

^{📍 sys/mem/cell}

---

The control object begins in Idle. A caller then arms it with a logical index, making it Armed. The first worker that successfully try_claims the request transitions it to Claimed.

Variants

Idle = 0

No request is currently active.

Armed = 1

A request is active and waiting for a winning replica.

Claimed = 2

A replica has already claimed the current request.

Implementations

impl MemHedgeState

pub const fn as_u8(self) -> u8

Returns the compact integer representation of this state.

pub const fn from_u8(value: u8) -> Option<Self>

Decodes a compact integer representation into a hedge state.

Trait Implementations

impl Clone for MemHedgeState

fn clone(&self) -> MemHedgeState

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for MemHedgeState

impl Debug for MemHedgeState

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

Formats the value using the given formatter.

impl Default for MemHedgeState

fn default() -> MemHedgeState

Returns the “default value” for a type.

impl Eq for MemHedgeState

impl Hash for MemHedgeState

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for MemHedgeState

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