Struct Stake 

#[repr(C)]
pub struct Stake {
    pub delegation: Delegation,
    pub credits_observed: u64,
}

Fields

delegation: Delegation

credits_observed: u64

credits observed is credits from vote account state when delegated or redeemed

Implementations

impl Stake

pub fn stake<T: StakeHistoryGetEntry>( &self, epoch: Epoch, history: &T, new_rate_activation_epoch: Option<Epoch>, ) -> u64

👎Deprecated since 3.2.0:

Use stake_v2() instead

pub fn stake_v2<T: StakeHistoryGetEntry>( &self, epoch: Epoch, history: &T, new_rate_activation_epoch: Option<Epoch>, ) -> u64

pub fn split( &mut self, remaining_stake_delta: u64, split_stake_amount: u64, ) -> Result<Self, StakeError>

pub fn deactivate(&mut self, epoch: Epoch) -> Result<(), StakeError>

impl Distribution<Stake> for StandardUniform

fn sample<R: Rng + ?Sized>(&self, rng: &mut R) -> Stake

Generate a random value of T, using rng as the source of randomness.

fn sample_iter<R>(self, rng: R) -> Iter<Self, R, T>

where R: Rng, Self: Sized,
