Struct solana_sdk::clock::Clock

pub struct Clock {
    pub slot: u64,
    pub epoch_start_timestamp: i64,
    pub epoch: u64,
    pub leader_schedule_epoch: u64,
    pub unix_timestamp: i64,
}

Clock represents network time. Members of Clock start from 0 upon network boot. The best way to map Clock to wallclock time is to use current Slot, as Epochs vary in duration (they start short and grow as the network progresses).

Fields

slot: u64

the current network/bank Slot

epoch_start_timestamp: i64

the timestamp of the first Slot in this Epoch

epoch: u64

the bank Epoch

leader_schedule_epoch: u64

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

unix_timestamp: i64

originally computed from genesis creation time and network time in slots (drifty); corrected using validator timestamp oracle as of timestamp_correction and timestamp_bounding features

Trait Implementations

impl Clone for Clock

fn clone(&self) -> Clock

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<(), Error>

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<Clock, <__D as Deserializer<'de>>::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 as Serializer>::Ok, <__S as Serializer>::Error>where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Sysvar for Clock

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

fn size_of() -> usize

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

Deserializes a sysvar from its AccountInfo.

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

impl SysvarId for Clock

fn id() -> Pubkey

fn check_id(pubkey: &Pubkey) -> bool

impl Eq for Clock

impl StructuralEq for Clock

impl StructuralPartialEq for Clock
