pub const RMW_SELECTOR_CAP: usize = 32;Expand description
Capacity of a backend selector name, matching Executor::primary_rmw_name.
issue 0687 — the READER moved to nros::rmw_selector (it needs a process
environment, which this crate no longer has), but the CAP belongs here: it
is the executor’s own identity storage, and a selector longer than this
cannot name a registry slot.
