Struct 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).
