Struct Handle 

#[non_exhaustive]
pub struct Handle {
    pub backend: BackendTag,
    pub kind: HandleKind,
    pub opaque: HandleOpaque,
}

Opaque attempt cookie held by the worker for the duration of an attempt. Produced by claim / claim_from_reclaim / suspend; borrowed by every op (renew, progress, append_frame, complete, fail, cancel, suspend, delay, wait_children, observe_signals, report_usage).

See RFC-012 §4.1 for the round-4 design — terminal ops borrow rather than consume so callers can retry after a transport error.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

backend: BackendTag

kind: HandleKind

opaque: HandleOpaque

Implementations

impl Handle

pub fn new(backend: BackendTag, kind: HandleKind, opaque: HandleOpaque) -> Self

Construct a new Handle. Called by backend impls only; consumer code receives Handles from claim / suspend / claim_from_reclaim.

Trait Implementations

impl Clone for Handle

fn clone(&self) -> Handle

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Handle

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

Formats the value using the given formatter.

impl Hash for Handle

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 Handle

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