}Expand description
Configuration trait of this pallet.
The main purpose of this trait is to act as an interface between this pallet and the runtime in which it is embedded in. A type, function, or constant in this trait is essentially left to be configured by the runtime that includes this pallet.
Consequently, a runtime that wants to include this pallet must implement this trait.
Required Associated Types§
Sourcetype RuntimeEvent: From<Event<Self>> + IsType<<Self as Config>::RuntimeEvent>
type RuntimeEvent: From<Event<Self>> + IsType<<Self as Config>::RuntimeEvent>
The overarching event type.
Sourcetype ValidatorId: Member + Parameter + MaybeSerializeDeserialize + MaxEncodedLen + TryFrom<Self::AccountId>
type ValidatorId: Member + Parameter + MaybeSerializeDeserialize + MaxEncodedLen + TryFrom<Self::AccountId>
A stable ID for a validator.
Sourcetype ValidatorIdOf: Convert<Self::AccountId, Option<Self::ValidatorId>>
type ValidatorIdOf: Convert<Self::AccountId, Option<Self::ValidatorId>>
A conversion from account ID to validator ID.
It is also a means to check that an account id is eligible to set session keys, through
being associated with a validator id. To disable this check, use
[sp_runtime::traits::ConvertInto].
Its cost must be at most one storage read.
Sourcetype ShouldEndSession: ShouldEndSession<BlockNumberFor<Self>>
type ShouldEndSession: ShouldEndSession<BlockNumberFor<Self>>
Indicator for when to end the session.
Sourcetype NextSessionRotation: EstimateNextSessionRotation<BlockNumberFor<Self>>
type NextSessionRotation: EstimateNextSessionRotation<BlockNumberFor<Self>>
Something that can predict the next session rotation. This should typically come from
the same logical unit that provides ShouldEndSession, yet, it gives a best effort
estimate. It is helpful to implement [EstimateNextNewSession].
Sourcetype SessionManager: SessionManager<Self::ValidatorId>
type SessionManager: SessionManager<Self::ValidatorId>
Handler for managing new session.
Sourcetype SessionHandler: SessionHandler<Self::ValidatorId>
type SessionHandler: SessionHandler<Self::ValidatorId>
Handler when a session has changed.
Sourcetype DisablingStrategy: DisablingStrategy<Self>
type DisablingStrategy: DisablingStrategy<Self>
DisablingStragegy controls how validators are disabled
Sourcetype WeightInfo: WeightInfo
type WeightInfo: WeightInfo
Weight information for extrinsics in this pallet.
Sourcetype Currency: Inspect<Self::AccountId> + HoldMutate<Self::AccountId, Reason: From<HoldReason>>
type Currency: Inspect<Self::AccountId> + HoldMutate<Self::AccountId, Reason: From<HoldReason>>
The currency type for placing holds when setting keys.
Sourcetype KeyDeposit: Get<<<Self as Config>::Currency as Inspect<<Self as Config>::AccountId>>::Balance>
type KeyDeposit: Get<<<Self as Config>::Currency as Inspect<<Self as Config>::AccountId>>::Balance>
The amount to be held when setting keys.
Dyn Compatibility§
This trait is not dyn compatible.
In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
