Struct frame_system::AccountInfo

pub struct AccountInfo<Index, AccountData> {
    pub nonce: Index,
    pub consumers: RefCount,
    pub providers: RefCount,
    pub sufficients: RefCount,
    pub data: AccountData,
}

Information of an account.

Fields

nonce: Index

The number of transactions this account has sent.

consumers: RefCount

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

providers: RefCount

The number of other modules that allow this account to exist. The account may not be reaped until this and sufficients are both zero.

sufficients: RefCount

The number of modules that allow this account to exist for their own purposes only. The account may not be reaped until this and providers are both zero.

data: AccountData

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

Trait Implementations

impl<Index: Clone, AccountData: Clone> Clone for AccountInfo<Index, AccountData>

fn clone(&self) -> AccountInfo<Index, AccountData>

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<Index, AccountData> Debug for AccountInfo<Index, AccountData>where
    Index: Debug,
    AccountData: Debug,

fn fmt(&self, fmt: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<Index, AccountData> Decode for AccountInfo<Index, AccountData>where
    Index: Decode,
    AccountData: Decode,

fn decode<__CodecInputEdqy: Input>(
    __codec_input_edqy: &mut __CodecInputEdqy
) -> Result<Self, Error>

Attempt to deserialise the value from input.

fn decode_into<I>(
    input: &mut I,
    dst: &mut MaybeUninit<Self>
) -> Result<DecodeFinished, Error>where
    I: Input,

Attempt to deserialize the value from input into a pre-allocated piece of memory.

fn skip<I>(input: &mut I) -> Result<(), Error>where
    I: Input,

Attempt to skip the encoded value from input.

fn encoded_fixed_size() -> Option<usize>

Returns the fixed encoded size of the type.

impl<Index: Default, AccountData: Default> Default for AccountInfo<Index, AccountData>

fn default() -> AccountInfo<Index, AccountData>

Returns the “default value” for a type.

impl<Index, AccountData> Encode for AccountInfo<Index, AccountData>where
    Index: Encode,
    AccountData: Encode,

fn size_hint(&self) -> usize

If possible give a hint of expected size of the encoding.

fn encode_to<__CodecOutputEdqy: Output + ?Sized>(
    &self,
    __codec_dest_edqy: &mut __CodecOutputEdqy
)

Convert self to a slice and append it to the destination.

fn encode(&self) -> Vec<u8, Global>

Convert self to an owned vector.

fn using_encoded<R, F>(&self, f: F) -> Rwhere
    F: FnOnce(&[u8]) -> R,

Convert self to a slice and then invoke the given closure with it.

fn encoded_size(&self) -> usize

Calculates the encoded size.

impl<Index, AccountData> MaxEncodedLen for AccountInfo<Index, AccountData>where
    Index: MaxEncodedLen,
    AccountData: MaxEncodedLen,

fn max_encoded_len() -> usize

Upper bound, in bytes, of the maximum encoded size of this item.

impl<Index: PartialEq, AccountData: PartialEq> PartialEq<AccountInfo<Index, AccountData>> for AccountInfo<Index, AccountData>

fn eq(&self, other: &AccountInfo<Index, AccountData>) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl<Index, AccountData> TypeInfo for AccountInfo<Index, AccountData>where
    Index: TypeInfo + 'static,
    AccountData: TypeInfo + 'static,

type Identity = AccountInfo<Index, AccountData>

The type identifying for which type info is provided.

fn type_info() -> Type
