Fields

voter_pubkey: Pubkey

to whom the stake is delegated

stake: u64

activated stake amount, set at delegate() time

activation_epoch: Epoch

epoch at which this stake was activated, std::Epoch::MAX if is a bootstrap stake

deactivation_epoch: Epoch

epoch the stake was deactivated, std::Epoch::MAX if not deactivated

warmup_cooldown_rate: f64

how much stake we can activate per-epoch as a fraction of currently effective stake
