Struct pallet_timestamp::pallet::Pallet

pub struct Pallet<T>(_);

The pallet implementing the on-chain logic.

Implementations

impl<T: Config> Pallet<T>

pub fn set(origin: OriginFor<T>, now: T::Moment) -> DispatchResult

Set the current time.

This call should be invoked exactly once per block. It will panic at the finalization phase, if this call hasn’t been invoked by that time.

The timestamp should be greater than the previous one by the amount specified by MinimumPeriod.

The dispatch origin for this call must be Inherent.

• O(1) (Note that implementations of OnTimestampSet must also be O(1))
• 1 storage read and 1 storage mutation (codec O(1)). (because of DidUpdate::take in on_finalize)
• 1 event handler on_timestamp_set. Must be O(1).

impl<T: Config> Pallet<T>

pub fn now() -> T::Moment

Current time for the current block.

impl<T: Config> Pallet<T>

pub fn get() -> T::Moment

Get the current time for the current block.

NOTE: if this function is called prior to setting the timestamp, it will return the timestamp of the previous block.

pub fn set_timestamp(now: T::Moment)

Set the timestamp to something in particular. Only used for tests.

Trait Implementations

impl<T> Benchmarking for Pallet<T>where
    T: Config + Config,

fn benchmarks(extra: bool) -> Vec<BenchmarkMetadata>

Get the benchmarks available for this pallet. Generally there is one benchmark per extrinsic, so these are sometimes just called “extrinsics”.

fn run_benchmark(
    extrinsic: &[u8],
    c: &[(BenchmarkParameter, u32)],
    whitelist: &[TrackedStorageKey],
    verify: bool,
    internal_repeats: u32
) -> Result<Vec<BenchmarkResult>, BenchmarkError>

Run the benchmarks for this pallet.

impl<T> Clone for Pallet<T>

fn clone(&self) -> Self

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

impl<T> Debug for Pallet<T>

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

Formats the value using the given formatter.

impl<T: Config> GetStorageVersion for Pallet<T>

fn current_storage_version() -> StorageVersion

Returns the current storage version as supported by the pallet.

fn on_chain_storage_version() -> StorageVersion

impl<T: Config> Hooks<<T as Config>::BlockNumber> for Pallet<T>

fn on_initialize(_n: BlockNumberFor<T>) -> Weight

dummy on_initialize to return the weight used in on_finalize.

fn on_finalize(_n: BlockNumberFor<T>)

• O(1)
• 1 storage deletion (codec O(1)).

fn on_idle(_n: BlockNumber, _remaining_weight: Weight) -> Weight

This will be run when the block is being finalized (before on_finalize). Implement to have something happen using the remaining weight. Will not fire if the remaining weight is 0. Return the weight used, the hook will subtract it from current weight used and pass the result to the next on_idle hook if it exists.

fn on_runtime_upgrade() -> Weight

Perform a module upgrade.

fn try_state(_n: BlockNumber) -> Result<(), &'static str>

Execute the sanity checks of this pallet, per block.

fn pre_upgrade() -> Result<(), &'static str>

Execute some pre-checks prior to a runtime upgrade.

fn post_upgrade() -> Result<(), &'static str>

Execute some post-checks after a runtime upgrade.

fn offchain_worker(_n: BlockNumber)

Implementing this function on a module allows you to perform long-running tasks that make (by default) validators generate transactions that feed results of those long-running computations back on chain.

fn integrity_test()

Run integrity test.

impl<T: Config> IntegrityTest for Pallet<T>

fn integrity_test()

Run integrity test.

impl<T: Config> OffchainWorker<<T as Config>::BlockNumber> for Pallet<T>

fn offchain_worker(n: <T as Config>::BlockNumber)

This function is being called after every block import (when fully synced).

impl<T: Config> OnFinalize<<T as Config>::BlockNumber> for Pallet<T>

fn on_finalize(n: <T as Config>::BlockNumber)

The block is being finalized. Implement to have something happen.

impl<T: Config> OnGenesis for Pallet<T>

fn on_genesis()

Something that should happen at genesis.

impl<T: Config> OnIdle<<T as Config>::BlockNumber> for Pallet<T>

fn on_idle(n: <T as Config>::BlockNumber, remaining_weight: Weight) -> Weight

The block is being finalized. Implement to have something happen in case there is leftover weight. Check the passed remaining_weight to make sure it is high enough to allow for your pallet’s extra computation.

impl<T: Config> OnInitialize<<T as Config>::BlockNumber> for Pallet<T>

fn on_initialize(n: <T as Config>::BlockNumber) -> Weight

The block is being initialized. Implement to have something happen.

impl<T: Config> OnRuntimeUpgrade for Pallet<T>

fn on_runtime_upgrade() -> Weight

Perform a module upgrade.

fn pre_upgrade() -> Result<(), &'static str>

Execute some pre-checks prior to a runtime upgrade.

fn post_upgrade() -> Result<(), &'static str>

Execute some post-checks after a runtime upgrade.

impl<T: Config> PalletInfoAccess for Pallet<T>

fn index() -> usize

Index of the pallet as configured in the runtime.

fn name() -> &'static str

Name of the pallet as configured in the runtime.

fn module_name() -> &'static str

Name of the Rust module containing the pallet.

fn crate_version() -> CrateVersion

Version of the crate containing the pallet.

All of the pallets’ information that this type represents.

impl<T> PartialEq<Pallet<T>> for Pallet<T>

fn eq(&self, other: &Self) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl<T: Config> ProvideInherent for Pallet<T>

type Error = InherentError

The error returned by check_inherent.

const INHERENT_IDENTIFIER: InherentIdentifier = INHERENT_IDENTIFIER

Check whether the given inherent is valid. Checking the inherent is optional and can be omitted by using the default implementation.
