Expand description

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§

source

type RuntimeEvent

The overarching event type.

source

type RuntimeHoldReason

The overarching hold reason.

source

type RuntimeFreezeReason

The overarching freeze reason.

source

type WeightInfo: WeightInfo

Weight information for extrinsics in this pallet.

source

type Balance: Parameter + Member + AtLeast32BitUnsigned + Codec + Default + Copy + MaybeSerializeDeserialize + Debug + MaxEncodedLen + TypeInfo + FixedPointOperand

The balance of an account.

source

type DustRemoval

Handler for the unbalanced reduction when removing a dust account.

source

type ExistentialDeposit

The minimum amount required to keep an account open. MUST BE GREATER THAN ZERO!

If you really need it to be zero, you can enable the feature insecure_zero_ed for this pallet. However, you do so at your own risk: this will open up a major DoS vector. In case you have multiple sources of provider references, you may also get unexpected behaviour if you set this to zero.

Bottom line: Do yourself a favour and make it at least one!

source

type ReserveIdentifier: Parameter + Member + MaxEncodedLen + Ord + Copy

The ID type for reserves.

Use of reserves is deprecated in favour of holds. See https://github.com/paritytech/substrate/pull/12951/

source

type FreezeIdentifier: Parameter + Member + MaxEncodedLen + Copy

The ID type for freezes.

source

type MaxLocks: Get<u32>

The maximum number of locks that should exist on an account. Not strictly enforced, but used for weight estimation.

Use of locks is deprecated in favour of freezes. See https://github.com/paritytech/substrate/pull/12951/

source

type MaxReserves: Get<u32>

The maximum number of named reserves that can exist on an account.

Use of reserves is deprecated in favour of holds. See https://github.com/paritytech/substrate/pull/12951/

source

type MaxFreezes: Get<u32>

The maximum number of individual freeze locks that can exist on an account at any time.

source

type DoneSlashHandler: DoneSlash<Self::RuntimeHoldReason, Self::AccountId, Self::Balance>

Allows callbacks to other pallets so they can update their bookkeeping when a slash occurs.

Object Safety§

This trait is not object safe.
