Struct solana_program::clock::Clock

#[repr(C)]
pub struct Clock {
    pub slot: Slot,
    pub epoch_start_timestamp: UnixTimestamp,
    pub epoch: Epoch,
    pub leader_schedule_epoch: Epoch,
    pub unix_timestamp: UnixTimestamp,
}

A representation of network time.

All members of Clock start from 0 upon network boot.

Fields

slot: Slot

The current Slot.

epoch_start_timestamp: UnixTimestamp

The timestamp of the first Slot in this Epoch.

epoch: Epoch

The current Epoch.

leader_schedule_epoch: Epoch

The future Epoch for which the leader schedule has most recently been calculated.

unix_timestamp: UnixTimestamp

The approximate real world time of the current slot.

This value was originally computed from genesis creation time and network time in slots, incurring a lot of drift. Following activation of the timestamp_correction and timestamp_bounding features it is calculated using a validator timestamp oracle.

Trait Implementations

impl Clone for Clock

fn clone(&self) -> Self

Returns a copy 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 Default for Clock

fn default() -> Clock

Returns the “default value” for a type.

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 PartialEq<Clock> for Clock

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

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>where
    __S: Serializer,

Serialize this value into the given Serde serializer.

impl Sysvar for Clock

fn get() -> Result<Self, ProgramError>

Load the sysvar directly from the runtime.

fn size_of() -> usize

The size in bytes of the sysvar as serialized account data.

fn from_account_info(
    account_info: &AccountInfo<'_>
) -> Result<Self, ProgramError>

Deserializes the sysvar from its AccountInfo.

fn to_account_info(&self, account_info: &mut AccountInfo<'_>) -> Option<()>

Serializes the sysvar to AccountInfo.

impl SysvarId for Clock

fn id() -> Pubkey

The Pubkey of the sysvar.

fn check_id(pubkey: &Pubkey) -> bool

Returns true if the given pubkey is the program ID.

impl Eq for Clock

impl StructuralEq for Clock

impl StructuralPartialEq for Clock
