Struct pallet_nicks::pallet::Pallet

pub struct Pallet<T>(_);

The pallet implementing the on-chain logic.

Implementations

impl<T: Config> Pallet<T>

pub fn set_name(origin: OriginFor<T>, name: Vec<u8>) -> DispatchResult

Set an account’s name. The name should be a UTF-8-encoded string by convention, though we don’t check it.

The name may not be more than T::MaxLength bytes, nor less than T::MinLength bytes.

If the account doesn’t already have a name, then a fee of ReservationFee is reserved in the account.

The dispatch origin for this call must be Signed.

• O(1).
• At most one balance operation.
• One storage read/write.
• One event.

pub fn clear_name(origin: OriginFor<T>) -> DispatchResult

Clear an account’s name and return the deposit. Fails if the account was not named.

The dispatch origin for this call must be Signed.

• O(1).
• One balance operation.
• One storage read/write.
• One event.

pub fn kill_name(
    origin: OriginFor<T>,
    target: <T::Lookup as StaticLookup>::Source
) -> DispatchResult

Remove an account’s name and take charge of the deposit.

Fails if who has not been named. The deposit is dealt with through T::Slashed imbalance handler.

The dispatch origin for this call must match T::ForceOrigin.

• O(1).
• One unbalanced handler (probably a balance transfer)
• One storage read/write.
• One event.

pub fn force_name(
    origin: OriginFor<T>,
    target: <T::Lookup as StaticLookup>::Source,
    name: Vec<u8>
) -> DispatchResult

Set a third-party account’s name with no deposit.

No length checking is done on the name.

The dispatch origin for this call must match T::ForceOrigin.

• O(1).
• At most one balance operation.
• One storage read/write.
• One event.

Trait Implementations

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

type Call = Call<T>

impl<T> Clone for Pallet<T>

fn clone(&self) -> Self

Returns a copy of the value.

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

Performs copy-assignment from source.

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

Returns the on-chain storage version of the pallet as stored in the storage.

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

fn on_finalize(_n: BlockNumber)

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

fn on_idle(_n: BlockNumber, _remaining_weight: u64) -> u64

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_initialize(_n: BlockNumber) -> u64

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

fn on_runtime_upgrade() -> u64

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.

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> ModuleErrorMetadata for Pallet<T>

fn metadata() -> &'static [ErrorMetadata]

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.

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 !=.
