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) -> Self

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 Clone for AccountID

fn clone(&self) -> AccountID

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for AccountID

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

Formats the value using the given formatter.

impl Default for AccountID

fn default() -> AccountID

Returns the “default value” for a type.

impl From<u64> for AccountID

fn from(value: u64) -> Self

Converts to this type from the input type.

impl Hash for AccountID

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Into<u64> for AccountID

fn into(self) -> u64

Converts this type into the (usually inferred) input type.

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,

Restrict a value to a certain interval.

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 le(&self, other: &Rhs) -> bool

Tests less than or equal to (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.
