pub fn validate_command_target_id(resource_id: &str) -> Result<()>Expand description
Reject a command-target resource id that would break the :-delimited key
grammar used by the pending index (target:{dep}:{rid}:pending:…) and the
idempotency key ({dep}:{rid}:{command}:{key}).
An id containing : could forge or collide with another target’s key
segments, so it is rejected at the commands layer with a typed error. Only
the delimiter that can forge index segments is enforced at this layer.
