}Fields (Non-exhaustive)§
This struct is marked as non-exhaustive
Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional 
Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.flags: __u64§mode: __u64§resolve: __u64
