Item information entry

ISO/IEC 14496-12 - 8.11.6

Fields

full_header: FullBoxHeader

The full box header.

item_id: Option<u32>

Contains either 0 for the primary resource (e.g., the XML contained in an XMLBox) or the ID of the item for which the following information is defined.

item_protection_index: u16

Contains either 0 for an unprotected item, or the index, with value 1 indicating the first entry, into the ItemProtectionBox defining the protection applied to this item (the first box in the ItemProtectionBox has the index 1).

item_type: [u8; 4]

A 32-bit value, typically 4 printable characters, that is a defined valid item type indicator, such as ‘mime’.

item_name: Utf8String

The symbolic name of the item (source file for file delivery transmissions).

item: Option<ItemInfoEntryItem>

The item information.

extension_type: Option<[u8; 4]>

A four character code that identifies the extension fields.

extension: Option<ItemInfoExtension<'a>>

The extension.

Trait Implementations

impl<'a> Debug for ItemInfoEntry<'a>

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

Formats the value using the given formatter.

impl<'a> Deserialize<'a> for ItemInfoEntry<'a>

fn deserialize<R>(reader: R) -> Result<Self>

where R: ZeroCopyReader<'a>,

Deserialize a value from the given zero-copy reader.

impl<'a> DeserializeSeed<'a, BoxHeader> for ItemInfoEntry<'a>

fn deserialize_seed<R>(reader: R, _seed: BoxHeader) -> Result<Self>

where R: ZeroCopyReader<'a>,

Deserialize a value from the given zero-copy reader using the provided seed.

impl<'a> IsoBox for ItemInfoEntry<'a>

const TYPE: BoxType

The box type of this box.

fn add_header_size(payload_size: usize) -> usize

This function calculates the header size, adds it to the given payload size and return the result.

fn box_header(&self) -> BoxHeader

Constructs a BoxHeader for this box.

fn serialize_box_header<W>(&self, writer: W) -> Result<()>

where W: Write,

Serializes the box header returned by IsoBox::box_header to the given writer.

impl IsoSized for ItemInfoEntry<'_>

fn size(&self) -> usize

Returns the size of the type when serialized.

impl<'a> PartialEq for ItemInfoEntry<'a>

fn eq(&self, other: &ItemInfoEntry<'a>) -> 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 Serialize for ItemInfoEntry<'_>

fn serialize<W>(&self, writer: W) -> Result<()>

where W: Write,

Serialize the value into the given writer.
