Hi,
I have come to notice that some structs in btrfs.h have get and set methods.
For instance
```
struct btrfs_index {
btrfs_key key;
uint64 logical_address;
uint64 generation;
uint64 LogicalAddress() const
{ return B_LENDIAN_TO_HOST_INT64(logical_address); }
uint64 Generation() const
{ return B_LENDIAN_TO_HOST_INT64(generation); }
void SetLogicalAddress(uint64 address)
{ logical_address = B_HOST_TO_LENDIAN_INT64(address); }
void SetGeneration(uint64 gen)
{ generation = B_HOST_TO_LENDIAN_INT64(gen); }
} _PACKED;
```
While some other structs do not. For example
```
struct btrfs_timespec {
uint64 seconds;
uint32 nanoseconds;
} _PACKED;
```
What is the criteria for having get and set methods?
Thank you
