Struct account_compression::processor::initialize_address_merkle_tree::EpochSchedule

#[repr(C)]
pub struct EpochSchedule {
    pub slots_per_epoch: u64,
    pub leader_schedule_slot_offset: u64,
    pub warmup: bool,
    pub first_normal_epoch: u64,
    pub first_normal_slot: u64,
}

Fields

slots_per_epoch: u64

The maximum number of slots in each epoch.

leader_schedule_slot_offset: u64

A number of slots before beginning of an epoch to calculate a leader schedule for that epoch.

warmup: bool

Whether epochs start short and grow.

first_normal_epoch: u64

The first epoch after the warmup period.

Basically: log2(slots_per_epoch) - log2(MINIMUM_SLOTS_PER_EPOCH).

first_normal_slot: u64

The first slot after the warmup period.

Basically: MINIMUM_SLOTS_PER_EPOCH * (2.pow(first_normal_epoch) - 1).

pub fn get_slots_in_epoch(&self, epoch: u64) -> u64

get the length of the given epoch (in slots)

Trait Implementations

impl AbiExample for EpochSchedule

fn example() -> EpochSchedule

impl Clone for EpochSchedule

fn clone(&self) -> EpochSchedule

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for EpochSchedule

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

Formats the value using the given formatter.

impl Default for EpochSchedule

fn default() -> EpochSchedule

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for EpochSchedule

fn deserialize<__D>( __deserializer: __D, ) -> Result<EpochSchedule, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for EpochSchedule

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

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 EpochSchedule

fn get() -> Result<EpochSchedule, 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 EpochSchedule

fn id() -> Pubkey

The Pubkey of the sysvar.

fn check_id(pubkey: &Pubkey) -> bool

Returns true if the given pubkey is the program ID.
