Module pallet

The pallet module in each FRAME pallet hosts the most important items needed to construct this pallet.

The main components of this pallet are:

• Pallet, which implements all of the dispatchable extrinsics of the pallet, among other public functions.
  • The subset of the functions that are dispatchable can be identified either in the dispatchables module or in the Call enum.
• storage_types, which contains the list of all types that are representing a storage item. Otherwise, all storage items are listed among Type Definitions.
• Config, which contains the configuration trait of this pallet.
• [Event] and Error, which are listed among the Enums.

Modules

dispatchables

Auto-generated docs-only module listing all defined dispatchables for this pallet.

storage_types

Auto-generated docs-only module listing all (public and private) defined storage types for this pallet.

Structs

GenesisConfig

Can be used to configure the genesis state of this pallet.

Pallet

The BABE Pallet

Enums

Call

Contains a variant per dispatchable extrinsic that this pallet has.

Error

The Error enum of this pallet.

Traits

Config

Configuration trait of this pallet.

Type Aliases

AuthorVrfRandomness

This field should always be populated during block processing unless secondary plain slots are enabled (which don’t contain a VRF output).

Authorities

Current epoch authorities.

CurrentSlot

Current slot number.

EpochConfig

The configuration for the current epoch. Should never be None as it is initialized in genesis.

EpochIndex

Current epoch index.

EpochStart

The block numbers when the last and current epoch have started, respectively N-1 and N. NOTE: We track this is in order to annotate the block number when a given pool of entropy was fixed (i.e. it was known to chain observers). Since epochs are defined in slots, which may be skipped, the block numbers may not line up with the slot numbers.

GenesisSlot

The slot at which the first epoch actually started. This is 0 until the first block of the chain.

Initialized

Temporary value (cleared at block finalization) which is Some if per-block initialization has already been called for current block.

Lateness

How late the current block is compared to its parent.

ModuleDeprecated

Type alias to Pallet, to be used by construct_runtime.

NextAuthorities

Next epoch authorities.

NextEpochConfig

The configuration for the next epoch, None if the config will not change (you can fallback to EpochConfig instead in that case).

NextRandomness

Next epoch randomness.

PendingEpochConfigChange

Pending epoch configuration change that will be applied when the next epoch is enacted.

Randomness

The epoch randomness for the current epoch.

SegmentIndex

Randomness under construction.

SkippedEpochs

A list of the last 100 skipped epochs and the corresponding session index when the epoch was skipped.

UnderConstruction

TWOX-NOTE: SegmentIndex is an increasing integer, so this is okay.
