Module pallet_babe::pallet

source ·
Expand description

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.

Re-exports§

  • pub use __tt_error_token_1 as tt_error_token;
  • pub use __tt_default_parts_7 as tt_default_parts;
  • pub use __tt_extra_parts_7 as tt_extra_parts;
  • pub use __tt_default_parts_v2_7 as tt_default_parts_v2;

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§

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.
