Struct btrfs_diskformat::Item

#[repr(C, packed)]pub struct Item {
    pub key: Key,
    pub offset: U32<LE>,
    pub size: U32<LE>,
}

For leaf nodes, the node header is followed by a dynamic number of items.

The item data is stored at the end of the node, as pointed to by the offset and size. The contents of the item are specified in the key.

Fields

key: Key

The key that contains the ID and contents of this Item.

offset: U32<LE>

Offset relative to the end of the header.

size: U32<LE>

The size of the data.
