### 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

package structs

// HostLayout marks a struct as using host memory layout. A struct with a
// field of type HostLayout will be laid out in memory according to host
// expectations, generally following the host's C ABI.
//
// HostLayout does not affect layout within any other struct-typed fields
// of the containing struct, nor does it affect layout of structs
// containing the struct marked as host layout.
//
