### New structs package

The new [structs] package provides
types for struct fields that modify properties of
the containing struct type such as memory layout.

In this release, the only such type is
[`HostLayout`](/pkg/structs#HostLayout)
which indicates that a structure with a field of that
type has a layout that conforms to host platform

// WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied.
// See the License for the specific language governing permissions and
// limitations under the License.

/*
struct.go contains functions for traversing and modifying trees of Go structs.
*/
