Struct 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 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 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 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.

impl<'de, WincodeConfig: Config> SchemaRead<'de, WincodeConfig> for Clock

const TYPE_META: TypeMeta

Metadata about the type’s serialization.

type Dst = Clock

fn read( reader: impl Reader<'de>, dst: &mut MaybeUninit<Self::Dst>, ) -> ReadResult<()>

Read into dst from reader.

fn get(reader: impl Reader<'de>) -> Result<Self::Dst, ReadError>

Read Self::Dst from reader into a new Self::Dst.

impl<WincodeConfig: Config> SchemaWrite<WincodeConfig> for Clock

const TYPE_META: TypeMeta

Metadata about the type’s serialization.

type Src = Clock

fn size_of(src: &Self::Src) -> WriteResult<usize>

Get the serialized size of Self::Src.

fn write(writer: impl Writer, src: &Self::Src) -> WriteResult<()>

Write Self::Src to writer.

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 SysvarId for Clock

Available on crate feature sysvar only.

fn id() -> Address

The Address of the sysvar.

fn check_id(address: &Address) -> bool

Returns true if the given address is the ID.

impl<WincodeConfig: Config> ZeroCopy<WincodeConfig> for Clock

where for<'_wincode_internal> Slot: ZeroCopy<WincodeConfig>, for<'_wincode_internal, '_wincode_internal> UnixTimestamp: ZeroCopy<WincodeConfig>, for<'_wincode_internal, '_wincode_internal> Epoch: ZeroCopy<WincodeConfig>, for<'_wincode_internal> Assert<{ _ }>: IsTrue,

fn from_bytes<'de>(bytes: &'de [u8], config: C) -> Result<&'de Self, ReadError>

where Self: Sized + SchemaRead<'de, C, Dst = Self>,

Like crate::ZeroCopy::from_bytes, but allows the caller to provide a custom configuration.

fn from_bytes_mut<'de>( bytes: &'de mut [u8], config: C, ) -> Result<&'de mut Self, ReadError>

where Self: Sized + SchemaRead<'de, C, Dst = Self>,

Like crate::ZeroCopy::from_bytes_mut, but allows the caller to provide a custom configuration.

impl Eq for Clock
