Struct AccountID 

pub struct AccountID(/* private fields */);

Account ID is a unique integer identifier for an account. Every account has one and only one account identifier. This is distinct from an account’s “address”. An account may actually have multiple addresses in different “address spaces” from the point of view of an external user, but an account always has one unique account ID. The account ID zero is reserved for the “null account” meaning that the account is not valid or does not exist.

Implementations

impl AccountID

pub const EMPTY: AccountID

The empty account ID.

pub const fn new(id: u64) -> AccountID

Creates a new account ID from the given integer.

pub fn is_empty(&self) -> bool

Returns true if the account ID is zero. The account ID zero is reserved for the “null account” meaning that the account is not valid or does not exist.

Trait Implementations

impl KeyFieldValue for AccountID

fn encode<'a>( key: &<AccountID as ObjectFieldValue>::In<'a>, writer: &mut ReverseSliceWriter<'_>, ) -> Result<(), EncodeError>

Encode the key segment as a non-terminal segment.

fn decode<'a>( reader: &mut &'a [u8], memory_manager: &'a MemoryManager, ) -> Result<<AccountID as ObjectFieldValue>::Out<'a>, DecodeError>

Decode the key segment as a non-terminal segment.

fn out_size<'a>(key: &<AccountID as ObjectFieldValue>::In<'a>) -> usize

Get the size of the key segment as a non-terminal segment.

fn encode_terminal<'a>( key: &Self::In<'a>, writer: &mut ReverseSliceWriter<'_>, ) -> Result<(), EncodeError>

Encode the key segment as the terminal segment.

fn decode_terminal<'a>( reader: &mut &'a [u8], memory_manager: &'a MemoryManager, ) -> Result<Self::Out<'a>, DecodeError>

Decode the key segment as the terminal segment.

fn out_size_terminal<'a>(key: &Self::In<'a>) -> usize

Get the size of the key segment as the terminal segment.

impl ObjectFieldValue for AccountID

type In<'a> = AccountID

The type that is used when inputting object values to functions.

type Out<'a> = AccountID

The type that is used in function return values.

impl Ord for AccountID

fn cmp(&self, other: &AccountID) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

impl PartialEq for AccountID

fn eq(&self, other: &AccountID) -> bool

Tests for self and other values to be equal, and is used by ==.

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

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

impl PartialOrd for AccountID

fn partial_cmp(&self, other: &AccountID) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.

type DecodeState = AccountID

In progress decoding state.

fn visit_decode_state( state: &mut <AccountID as SchemaValue<'a>>::DecodeState, decoder: &mut dyn Decoder<'a>, ) -> Result<(), DecodeError>

Decode the value from the decoder.

fn finish_decode_state( state: <AccountID as SchemaValue<'a>>::DecodeState, mem: &'a MemoryManager, ) -> Result<AccountID, DecodeError>
