Fields

account_meta_format: AccountMetaFormat

The format of the account meta entry.

owners_block_format: OwnersBlockFormat

The format of the owners block.

index_block_format: IndexBlockFormat

The format of the account index block.

account_block_format: AccountBlockFormat

The format of the account block.

account_entry_count: u32

owner_entry_size: u32

The size of each owner entry.

index_block_offset: u64

The offset pointing to the first byte of the account index block.

owners_block_offset: u64

The offset pointing to the first byte of the owners block.

min_account_address: Pubkey

The smallest account address in this file.

max_account_address: Pubkey

The largest account address in this file.

hash: Hash

footer_size: u64
