Trait Implementations

impl<T> PalletInfoAccess for Pallet<T>

where T: Config,

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 name_hash() -> [u8; 16]

Two128 hash of name.

fn module_name() -> &'static str

Name of the Rust module containing the pallet.

fn crate_version() -> CrateVersion

Version of the crate containing the pallet.

impl<T> Debug for Pallet<T>

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

Formats the value using the given formatter.

impl<T> WhitelistedStorageKeys for Pallet<T>

where T: Config,

fn whitelisted_storage_keys() -> Vec<TrackedStorageKey>

Returns a Vec<TrackedStorageKey> indicating the storage keys that should be whitelisted during benchmarking. This means that those keys will be excluded from the benchmarking performance calculation.

impl<T> Randomness<<T as Config>::Hash, <<<T as Config>::Block as HeaderProvider>::HeaderT as Header>::Number> for Pallet<T>

where T: Config,

fn random( subject: &[u8] ) -> (<T as Config>::Hash, <<<T as Config>::Block as HeaderProvider>::HeaderT as Header>::Number)

Uses the vrf output of previous block to generate a random seed. The provided subject must have the property to uniquely generate different randomness given the same vrf output (e.g. relay block number).

In our case the subject is provided via Nimbus and consists of three parts: 1. Constant string *b“filter“ - to identify author-slot-filter pallet 2. First 2 bytes of index.to_le_bytes() when selecting the ith eligible author 3. First 4 bytes of slot_number.to_be_bytes()

Note: This needs to be updated when asynchronous backing is in effect, as it will be unsafe.

fn random_seed() -> (Output, BlockNumber)

Get the basic random seed.

where T: Config,

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

impl<T> GetStorageVersion for Pallet<T>

where T: Config,

type InCodeStorageVersion = NoStorageVersionSet

This type is generated by the pallet macro.

fn in_code_storage_version( ) -> <Pallet<T> as GetStorageVersion>::InCodeStorageVersion

Returns the in-code storage version as specified in the storage_version attribute, or [NoStorageVersionSet] if the attribute is missing.

fn on_chain_storage_version() -> StorageVersion

Returns the storage version of the pallet as last set in the actual on-chain storage.

fn current_storage_version() -> Self::InCodeStorageVersion

👎Deprecated: This method has been renamed to in_code_storage_version and will be removed after March 2024.

DEPRECATED: Use [Self::current_storage_version] instead.
