Struct VbsChunkHeader

#[repr(C)]
pub struct VbsChunkHeader {
    pub byte_count: u32,
    pub chunk_type: BootMeasurementType,
    pub reserved: u64,
}

Chunk that is measured to generate digest. These consist of a 16 byte header followed by data. This needs c style alignment to generate a consistent measurement. Defined by the following struct in C:

typedef struct _VBS_VM_BOOT_MEASUREMENT_CHUNK
{
    UINT32 ByteCount;
    VBS_VM_BOOT_MEASUREMENT_CHUNK_TYPE Type;
    UINT64 Reserved;

    union
    {
        VBS_VM_BOOT_MEASUREMENT_CHUNK_VP_REGISTER VpRegister;
        VBS_VM_BOOT_MEASUREMENT_CHUNK_VP_VTL_ENABLED VpVtlEnabled;
        VBS_VM_BOOT_MEASUREMENT_CHUNK_GPA_PAGE GpaPage;
    } u;
} VBS_VM_BOOT_MEASUREMENT_CHUNK, *PVBS_VM_BOOT_MEASUREMENT_CHUNK;
