typedef rcutils_error_state_t rcl_error_state_t

The error handling in RCL is just an alias to the error handling in rcutils.

Allocators given to functions in rcl are passed along to the error handling on a "best effort" basis. In some situations, like when NULL is passed for the allocator or something else that contains it, the allocator is not available to be passed to the RCL_SET_ERROR_MSG macro. In these cases, the default allocator rcl_get_default_allocator() is used. Since these are considered fatal errors, as opposed to errors that might occur during normal runtime, is should be okay to use the default allocator.
