Struct Clock 

pub struct Clock {
    pub id: UID,
    pub timestamp_ms: u64,
}

Singleton shared object that exposes time to Move calls. This object is found at address 0x6, and can only be read (accessed via an immutable reference) by entry functions.

Entry Functions that attempt to accept Clock by mutable reference or value will fail to verify, and honest validators will not sign or execute transactions that use Clock as an input parameter, unless it is passed by immutable reference.

Fields

id: UID

timestamp_ms: u64

The clock’s timestamp, which is set automatically by a system transaction every time consensus commits a schedule, or by sui::clock::increment_for_testing during testing.

Implementations

impl Clock

pub fn new(id: UID, timestamp_ms: u64) -> Self

Constructs a new Clock.

impl Clock

pub fn move_instance(self) -> MoveInstance<Self>

pub fn type_() -> ClockTypeTag

Trait Implementations

impl Clone for Clock

fn clone(&self) -> Clock

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Clock

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Clock

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for Clock

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

Formats the value using the given formatter.

impl HasKey for Clock

fn object_id(&self) -> Address

impl Hash for Clock

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 MoveStruct for Clock

type StructTag = ClockTypeTag

impl MoveType for Clock

type TypeTag = ClockTypeTag

fn from_bcs(bytes: &[u8]) -> Result<Self, Error>

Deserialize the contents of the Move type from BCS bytes.

fn into_bcs(self) -> Result<Vec<u8>, Error>

Consuming version of to_bcs.

fn to_bcs(&self) -> Result<Vec<u8>, Error>

Serialize the contents of the Move type to BCS bytes.

fn into_json(self) -> Value

Consuming version of to_json.

fn to_json(&self) -> Value

impl PartialEq for Clock

fn eq(&self, other: &Clock) -> 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.

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Tabled for Clock

const LENGTH: usize = 2usize

fn fields(&self) -> Vec<Cow<'_, str>>

Fields method must return a list of cells.

fn headers() -> Vec<Cow<'static, str>>

Headers must return a list of column names.
