pub const DECLARE_TIMEOUT: Duration;Expand description
How long a declaration may take before this crate calls it a failure.
A declare_subscriber/declare_queryable/declare_token that never
returns hangs the tool with nothing to report, which is exactly the shape
#341 fixed for zenoh::open — and OPEN_TIMEOUT is
the precedent this follows. Shorter than the open, because a declaration
happens against a session that is already up (#346).
