Field Documentation

union { ... }

The leaves/slots/buckets to be filed with leafs.

i32 ip4_fib_mtrie_8_ply_t_::dst_address_bits_base

The length of the ply's coviering prefix.

Also a measure of its depth If a leaf in a slot has a mask length longer than this then it is 'non-empty'. Otherwise it is the value of the cover.
