Enum HandleKind 

#[non_exhaustive]
pub enum HandleKind {
    Fresh,
    Resumed,
    Suspended,
}

Lifecycle kind carried inside a Handle. Backends validate kind on entry to each op and return EngineError::State on mismatch.

Replaces round-1’s compile-time Handle / ResumeHandle / SuspendToken type split (RFC-012 §4.1).

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Fresh

Fresh claim — returned by claim / claim_from_grant.

Resumed

Resumed from reclaim — returned by claim_from_reclaim.

Suspended

Suspended — returned by suspend. Terminal for the lease; resumption mints a new Handle via claim_from_reclaim.

Trait Implementations

impl Clone for HandleKind

fn clone(&self) -> HandleKind

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for HandleKind

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

Formats the value using the given formatter.

impl Hash for HandleKind

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 HandleKind

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