Struct ExecutorSizing 

pub struct ExecutorSizing {
    pub cbs: usize,
    pub sc: usize,
    pub arena: usize,
    pub nodes: usize,
}

Per-entry executor sizing — the entity counts an Executor is built to hold. Public + non-generic (the “C/C++ is a thin wrapper” principle): the entry / macro / FFI supplies these as plain usizes rather than as type/const generics C can’t name. Used to size + carve the backing.

cbs is capped at 64 by the executor’s u64 ready-set bitmask (asserted in [carve]-time / open_in).

Fields

cbs: usize

Callback-table slots (entries, the per-entry SC bindings, and the per-callback-group sched table). ≤ 64.

sc: usize

Scheduling-context slots (sched_contexts + sporadic state tables).

arena: usize

Bump-allocator arena size in bytes.

nodes: usize

phase-409 — Node slots. One worst-case extra session, extra-session id, node-sched binding, dispatch slot, component slot and callback-group filter entry per Node, so ONE count covers all seven tables (that is the upper bound each of them already assumed under MAX_NODES).

Implementations

impl ExecutorSizing

pub const DEFAULT: ExecutorSizing

The build-time default (MAX_CBS/MAX_SC/ARENA_SIZE/MAX_NODES consts) — the backward-compatible size the alloc convenience constructors leak.

pub const fn u64_len(&self) -> usize

u64 words a backing must hold for this sizing (see executor_storage_u64_len).

Trait Implementations

impl Clone for ExecutorSizing

fn clone(&self) -> ExecutorSizing

Returns a duplicate of the value.

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

Performs copy-assignment from source.
