Struct ExtensibleArrayIndexBlock 

pub struct ExtensibleArrayIndexBlock {
    pub class_id: u8,
    pub header_addr: u64,
    pub elements: Vec<u64>,
    pub dblk_addrs: Vec<u64>,
    pub sblk_addrs: Vec<u64>,
}

Extensible array index block.

On-disk layout:

"EAIB"(4) + version=0(1) + class_id(1)
+ header_addr(sizeof_addr)
+ elements (idx_blk_elmts * raw_elmt_size bytes)
+ data_block_addresses (ndblk_addrs * sizeof_addr)
+ super_block_addresses (nsblk_addrs * sizeof_addr)
+ checksum(4)

Fields

class_id: u8

header_addr: u64

elements: Vec<u64>

Direct chunk addresses in the index block.

dblk_addrs: Vec<u64>

Data block addresses.

sblk_addrs: Vec<u64>

Super block addresses.
