Struct ItemLocationBoxItem

pub struct ItemLocationBoxItem {
    pub item_id: Option<u32>,
    pub construction_method: Option<u8>,
    pub data_reference_index: u16,
    pub base_offset: u64,
    pub extent_count: u16,
    pub extents: Vec<ItemLocationBoxExtent>,
}

Item in the ItemLocationBox.

Fields

item_id: Option<u32>

An arbitrary integer ‘name’ for this resource which can be used to refer to it (e.g. in a URL).

construction_method: Option<u8>

Taken from the set 0 (file), 1 (idat) or 2 (item).

data_reference_index: u16

Either zero (‘this file’) or an index, with value 1 indicating the first entry, into the data references in the DataInformationBox.

base_offset: u64

Provides a base value for offset calculations within the referenced data. If base_offset_size is 0, base_offset takes the value 0, i.e. it is unused.

extent_count: u16

Provides the count of the number of extents into which the resource is fragmented; it shall have the value 1 or greater.

extents: Vec<ItemLocationBoxExtent>

Extents in this item.

Implementations

impl ItemLocationBoxItem

pub fn size(&self, parent: &ItemLocationBox) -> usize

Calculates the size of this item, depending on the parent box.

Trait Implementations

impl Debug for ItemLocationBoxItem

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

Formats the value using the given formatter.

impl PartialEq for ItemLocationBoxItem

fn eq(&self, other: &ItemLocationBoxItem) -> 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.
