StakesView

Struct StakesView 

Source
pub struct StakesView(/* private fields */);
Expand description

Read-only view of the stake cache for external consumers (e.g., RPC handlers).

This type wraps a StakesHandle and exposes only read-only query methods. Mutation methods (insert_stake_account, insert_validator_account, freeze_stakes, request_epoch_rewards_init, etc.) are intentionally not exposed.

§Usage

External code (outside the svm-execution crate) should use Bank::stakes_view() to obtain a StakesView instead of accessing the full StakesHandle directly. This prevents accidental state corruption from RPC handlers or other non-transaction code paths.

Implementations§

Source§

impl StakesView

Source

pub fn new(handle: StakesHandle) -> Self

Create a new read-only view from a StakesHandle.

Source

pub fn get_stake_account_from_pending( &self, pubkey: &Pubkey, ) -> Option<StakeAccount>

Get a stake account starting from pending (next epoch state).

Searches: pending → frozen (newest to oldest) → baseline

Source

pub fn get_validator_account_from_pending( &self, pubkey: &Pubkey, ) -> Option<ValidatorAccount>

Get a validator account starting from pending (next epoch state).

Searches: pending → frozen (newest to oldest) → baseline

Source

pub fn get_all_validator_accounts_from_pending( &self, ) -> Vec<(Pubkey, ValidatorAccount)>

Get all validator accounts starting from pending (next epoch state).

Source

pub fn get_stake_account_from_last_frozen( &self, pubkey: &Pubkey, ) -> Option<StakeAccount>

Get a stake account starting from the last frozen epoch (current epoch state).

Searches: frozen (newest to oldest) → baseline. Skips pending.

Source

pub fn get_validator_account_from_last_frozen( &self, pubkey: &Pubkey, ) -> Option<ValidatorAccount>

Get a validator account starting from the last frozen epoch (current epoch state).

Searches: frozen (newest to oldest) → baseline. Skips pending.

Source

pub fn get_all_validator_accounts_from_last_frozen( &self, ) -> Vec<(Pubkey, ValidatorAccount)>

Get all validator accounts from the last frozen epoch (current epoch state).

Source

pub fn last_frozen_timestamp(&self) -> Option<u64>

Get the timestamp of the last frozen epoch (current epoch’s effective state).

Returns None if no frozen snapshots exist yet.
