Struct solana_runtime::epoch_accounts_hash::manager::Manager

pub struct Manager {
    state: Mutex<State>,
    cvar: Condvar,
}

Manage the epoch accounts hash

Handles setting when an EAH calculation is requested and when it completes. Also handles waiting for in-flight calculations to complete when the “stop” Bank must include it.

Fields

state: Mutex<State>

Current state of the epoch accounts hash

cvar: Condvar

This condition variable is used to wait for an in-flight EAH calculation to complete

Implementations

impl Manager

fn _new(state: State) -> Self

pub fn new_invalid() -> Self

Create a new epoch accounts hash manager, with the initial state set to Invalid

pub fn new_valid(epoch_accounts_hash: EpochAccountsHash, slot: Slot) -> Self

Create a new epoch accounts hash manager, with the initial state set to Valid

pub fn set_in_flight(&self, slot: Slot)

An epoch accounts hash calculation has been requested; update our state

pub fn set_valid(&self, epoch_accounts_hash: EpochAccountsHash, slot: Slot)

An epoch accounts hash calculation has completed; update our state

pub fn wait_get_epoch_accounts_hash(&self) -> EpochAccountsHash

Get the epoch accounts hash

If an EAH calculation is in-flight, then this call will block until it completes.

pub fn try_get_epoch_accounts_hash(&self) -> Option<EpochAccountsHash>

Get the epoch accounts hash

This fn does not block, and will only yield an EAH if the state is Valid

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

Formats the value using the given formatter.
