Implementations§
Source§impl<R: Runtime> PowManager<R>
impl<R: Runtime> PowManager<R>
Sourcepub(crate) fn new(
runtime: R,
nickname: HsNickname,
instance_dir: InstanceRawSubdir,
keymgr: Arc<KeyMgr>,
storage_handle: StorageHandle<PowManagerStateRecord>,
) -> Result<NewPowManager<R>, StartupError>
pub(crate) fn new( runtime: R, nickname: HsNickname, instance_dir: InstanceRawSubdir, keymgr: Arc<KeyMgr>, storage_handle: StorageHandle<PowManagerStateRecord>, ) -> Result<NewPowManager<R>, StartupError>
Create a new PowManager
.
Sourcepub(crate) fn launch(self: &Arc<Self>) -> Result<(), StartupError>
pub(crate) fn launch(self: &Arc<Self>) -> Result<(), StartupError>
Launch background task to rotate seeds.
Sourceasync fn main_loop_task(self: Arc<Self>)
async fn main_loop_task(self: Arc<Self>)
Main loop for rotating seeds.
Sourcefn make_next_expiration_time<Rng: RngCore + CryptoRng>(
rng: &mut Rng,
) -> SystemTime
fn make_next_expiration_time<Rng: RngCore + CryptoRng>( rng: &mut Rng, ) -> SystemTime
Make a randomized seed expiration time.
Sourcefn make_verifier(
keymgr: &Arc<KeyMgr>,
nickname: HsNickname,
time_period: TimePeriod,
seed: Seed,
) -> Option<Verifier>
fn make_verifier( keymgr: &Arc<KeyMgr>, nickname: HsNickname, time_period: TimePeriod, seed: Seed, ) -> Option<Verifier>
Make a ner Verifier
for a given TimePeriod
and Seed
.
If a key is not available for this TP, returns None.
This takes individual agruments instead of &self
to avoid getting into any trouble with
locking.
Sourcefn calculate_early_rotation_time(expiration_time: SystemTime) -> SystemTime
fn calculate_early_rotation_time(expiration_time: SystemTime) -> SystemTime
Calculate a time when we want to rotate a seed, slightly before it expires, in order to ensure that clients don’t ever download a seed that is already out of date.
Sourceasync fn rotate_seeds_if_expiring(&self) -> Option<SystemTime>
async fn rotate_seeds_if_expiring(&self) -> Option<SystemTime>
Rotate any seeds that will expire soon.
This also pokes the publisher when needed to cause rotated seeds to be published.
Returns the next time this function should be called again.
Sourcepub(crate) fn get_pow_params(
self: &Arc<Self>,
time_period: TimePeriod,
) -> Result<PowParams, InternalPowError>
pub(crate) fn get_pow_params( self: &Arc<Self>, time_period: TimePeriod, ) -> Result<PowParams, InternalPowError>
Get PowParams
for a given TimePeriod
.
If we don’t have any Seed
s for the requested period, generate them. This is the only
way that PowManager
learns about new TimePeriod
s.
Sourcefn check_solve(
self: &Arc<Self>,
solve: &ProofOfWorkV1,
) -> Result<(), PowSolveError>
fn check_solve( self: &Arc<Self>, solve: &ProofOfWorkV1, ) -> Result<(), PowSolveError>
Verify a PoW solve.
