Struct frame_system::AccountInfo

pub struct AccountInfo<Index, AccountData> {
    pub nonce: Index,
    pub refcount: RefCount,
    pub data: AccountData,
}

Information of an account.

Fields

nonce: Index

The number of transactions this account has sent.

refcount: RefCount

The number of other modules that currently depend on this account’s existence. The account cannot be reaped until this is zero.

data: AccountData

The additional data that belongs to this account. Used to store the balance(s) in a lot of chains.
