Type Alias RawServiceCallback 

pub type RawServiceCallback = unsafe extern "C" fn(*const u8, usize, *mut u8, usize, *mut usize, *mut c_void) -> bool;

Raw service callback that receives and produces CDR bytes.

Safety

• req is valid for req_len bytes
• resp is valid for resp_cap bytes (writable)
• resp_len is a valid pointer to write the response length

Returns true if the request was handled successfully.
