Struct Item

#[repr(C)]
pub struct Item { /* private fields */ }

This type is the base class responsible for libosmium’s custom memory management.

It stores an object’s dynamic size and its actual subclass as an enum.

Implementations

impl Item

pub fn as_bytes(&self) -> &[u8]

Get the item’s data as byte slice padded to aligned_size

pub fn aligned_size(&self) -> usize

Get the item’s dynamic size aligned to ALIGN_BYTES

pub fn byte_size(&self) -> u32

Get the item’s dynamic size

pub fn item_type(&self) -> ItemType

Get the item’s type

pub fn cast(&self) -> Option<ItemRef<'_>>

Convert an item’s reference into a reference of its actual subclass
