Struct Header

#[repr(C)]
pub struct Header {
    pub type: Type,
    pub length: u32,
    pub extra: u32,
    pub flags: Flags,
    pub reserved0: u32,
    pub reserved1: u32,
    pub magic: u32,
    pub crc32: u32,
}

Each header must be 8-byte aligned. The length field specifies the actual payload length and does not include the size of padding.

Fields

type: Type

ZBI_TYPE_* constant.

length: u32

Size of the payload immediately following this header. This does not include the header itself nor any alignment padding after the payload.

extra: u32

Type-specific extra data. Each type specifies the use of this field. When not explicitly specified, it should be zero.

flags: Flags

Flags for this item.

reserved0: u32

For future expansion. Set to 0.

reserved1: u32

magic: u32

Must be ZBI_ITEM_MAGIC.

crc32: u32

Must be the CRC32 of payload if ZBI_FLAGS_CRC32 is set, otherwise must be ZBI_ITEM_NO_CRC32.

Trait Implementations

impl Clone for Header

fn clone(&self) -> Header

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Header

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for Header

fn eq(&self, other: &Header) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Copy for Header

impl Eq for Header

impl IntoBytes for Header

where Type: IntoBytes, u32: IntoBytes, Flags: IntoBytes, (): PaddingFree<Header, { _ }>,
