Struct Handle 

pub struct Handle {
    pub pool_id: u32,
    pub handle_id: u32,
    pub generation: u32,
}

A pool-relative pool callback handle — pure data, no methods (D7).

(pool_id, handle_id) per D7/DR-2; the Rust pool adds a local generation (B32) so a recycled slotmap slot can be told apart from a stale handle (the pool frees a dropped node’s fn slot and reuses it). generation is a PER-LANGUAGE impl detail (D24), NOT part of the protocol/IDL Handle — it is wire-meaningless and is dropped at the wire boundary (a wired handle is re-resolved against the remote pool). User-approved Handle-widening 2026-05-29 (see CLEAN-SLATE.md). A node is NOT a handle; a handle is inert routing data.

Fields

pool_id: u32

pool_id field for pool id.

handle_id: u32

handle_id field for handle id.

generation: u32

Local slotmap generation (B32, per-language) — NOT in the protocol IDL.

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.
