Based on Config
. Auto-generated by
#[pallet::config(with_default)]
.
Can be used in tandem with
#[register_default_config]
and
#[derive_impl]
to derive test config traits
based on existing pallet config traits in a safe and developer-friendly way.
See here for more information and caveats about
the auto-generated DefaultConfig
trait and how it is generated.
Required Associated Types§
sourcetype RuntimeEvent
type RuntimeEvent
The aggregated event type of the runtime.
sourcetype BaseCallFilter
type BaseCallFilter
The basic call filter to use in Origin. All origins are built with this filter as base, except Root.
This works as a filter for each incoming call. The call needs to pass this filter in
order to dispatch. Otherwise it will be rejected with CallFiltered
. This can be
bypassed via dispatch_bypass_filter
which should only be accessible by root. The
filter can be composed of sub-filters by nesting for example
frame_support::traits::InsideBoth
, frame_support::traits::TheseExcept
or
frame_support::traits::EverythingBut
et al. The default would be
frame_support::traits::Everything
.
sourcetype BlockWeights: Get<BlockWeights>
type BlockWeights: Get<BlockWeights>
Block & extrinsics weights: base values and limits.
sourcetype BlockLength: Get<BlockLength>
type BlockLength: Get<BlockLength>
The maximum length of a block (in bytes).
sourcetype RuntimeOrigin
type RuntimeOrigin
The RuntimeOrigin
type used by dispatchable calls.
sourcetype RuntimeCall
type RuntimeCall
The aggregated RuntimeCall
type.
sourcetype RuntimeTask
type RuntimeTask
The aggregated RuntimeTask
type.
sourcetype Nonce: Parameter + Member + MaybeSerializeDeserialize + Debug + Default + MaybeDisplay + AtLeast32Bit + Copy + MaxEncodedLen
type Nonce: Parameter + Member + MaybeSerializeDeserialize + Debug + Default + MaybeDisplay + AtLeast32Bit + Copy + MaxEncodedLen
This stores the number of previous transactions associated with a sender account.
sourcetype Hash: Parameter + Member + MaybeSerializeDeserialize + Debug + MaybeDisplay + SimpleBitOps + Ord + Default + Copy + CheckEqual + Hash + AsRef<[u8]> + AsMut<[u8]> + MaxEncodedLen
type Hash: Parameter + Member + MaybeSerializeDeserialize + Debug + MaybeDisplay + SimpleBitOps + Ord + Default + Copy + CheckEqual + Hash + AsRef<[u8]> + AsMut<[u8]> + MaxEncodedLen
The output of the Hashing
function.
sourcetype Hashing: Hash<Output = Self::Hash> + TypeInfo
type Hashing: Hash<Output = Self::Hash> + TypeInfo
The hashing system (algorithm) being used in the runtime (e.g. Blake2).
sourcetype AccountId: Parameter + Member + MaybeSerializeDeserialize + Debug + MaybeDisplay + Ord + MaxEncodedLen
type AccountId: Parameter + Member + MaybeSerializeDeserialize + Debug + MaybeDisplay + Ord + MaxEncodedLen
The user account identifier type for the runtime.
sourcetype Lookup: StaticLookup<Target = Self::AccountId>
type Lookup: StaticLookup<Target = Self::AccountId>
Converting trait to take a source type and convert to AccountId
.
Used to define the type and conversion mechanism for referencing accounts in
transactions. It’s perfectly reasonable for this to be an identity conversion (with the
source type being AccountId
), but other pallets (e.g. Indices pallet) may provide more
functional/efficient alternatives.
sourcetype BlockHashCount
type BlockHashCount
Maximum number of block number to block hash mappings to keep (oldest pruned first).
sourcetype DbWeight: Get<RuntimeDbWeight>
type DbWeight: Get<RuntimeDbWeight>
The weight of runtime database operations the runtime can invoke.
sourcetype Version: Get<RuntimeVersion>
type Version: Get<RuntimeVersion>
Get the chain’s in-code version.
sourcetype PalletInfo
type PalletInfo
Provides information about the pallet setup in the runtime.
Expects the PalletInfo
type that is being generated by construct_runtime!
in the
runtime.
For tests it is okay to use ()
as type, however it will provide “useless” data.
sourcetype AccountData: Member + FullCodec + Clone + Default + TypeInfo + MaxEncodedLen
type AccountData: Member + FullCodec + Clone + Default + TypeInfo + MaxEncodedLen
Data to be associated with an account (other than nonce/transaction counter, which this pallet does regardless).
sourcetype OnNewAccount: OnNewAccount<Self::AccountId>
type OnNewAccount: OnNewAccount<Self::AccountId>
Handler for when a new account has just been created.
sourcetype OnKilledAccount: OnKilledAccount<Self::AccountId>
type OnKilledAccount: OnKilledAccount<Self::AccountId>
A function that is invoked when an account has been determined to be dead.
All resources should be cleaned up associated with the given account.
type SystemWeightInfo: WeightInfo
sourcetype SS58Prefix: Get<u16>
type SS58Prefix: Get<u16>
The designated SS58 prefix of this chain.
This replaces the “ss58Format” property declared in the chain spec. Reason is that the runtime should know about the prefix in order to make use of it as an identifier of the chain.
sourcetype OnSetCode
type OnSetCode
What to do if the runtime wants to change the code to something new.
The default (()
) implementation is responsible for setting the correct storage
entry and emitting corresponding event and log item. (see
Pallet::update_code_in_storage
).
It’s unlikely that this needs to be customized, unless you are writing a parachain using
Cumulus
, where the actual code change is deferred.
sourcetype MaxConsumers: ConsumerLimits
type MaxConsumers: ConsumerLimits
The maximum number of consumers allowed on a single account.
sourcetype SingleBlockMigrations: OnRuntimeUpgrade
type SingleBlockMigrations: OnRuntimeUpgrade
All migrations that should run in the next runtime upgrade.
These used to be formerly configured in Executive
. Parachains need to ensure that
running all these migrations in one block will not overflow the weight limit of a block.
The migrations are run before the pallet on_runtime_upgrade
hooks, just like the
OnRuntimeUpgrade
migrations.
sourcetype MultiBlockMigrator: MultiStepMigrator
type MultiBlockMigrator: MultiStepMigrator
The migrator that is used to run Multi-Block-Migrations.
Can be set to [pallet-migrations
] or an alternative implementation of the interface.
The diagram in frame_executive::block_flowchart
explains when it runs.
sourcetype PreInherents: PreInherents
type PreInherents: PreInherents
A callback that executes in every block directly before all inherents were applied.
See frame_executive::block_flowchart
for a in-depth explanation when it runs.
sourcetype PostInherents: PostInherents
type PostInherents: PostInherents
A callback that executes in every block directly after all inherents were applied.
See frame_executive::block_flowchart
for a in-depth explanation when it runs.
sourcetype PostTransactions: PostTransactions
type PostTransactions: PostTransactions
A callback that executes in every block directly after all transactions were applied.
See frame_executive::block_flowchart
for a in-depth explanation when it runs.
