Module pallet_session::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
dispatchablesmodule or in theCallenum. 
- The subset of the functions that are dispatchable can be identified either in the
 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.EventandError, which are listed among the Enums.
Modules
- Auto-generated docs-only module listing all defined dispatchables for this pallet.
 - Auto-generated docs-only module listing all (public and private) defined storage types for this pallet.
 
Structs
- Can be used to configure the genesis state of this pallet.
 - The
Palletstruct, the main type that implements traits and standalone functions within the pallet. 
Enums
- Contains a variant per dispatchable extrinsic that this pallet has.
 - Error for the session pallet.
 - The
Eventenum of this pallet 
Traits
- Configuration trait of this pallet.
 
Type Definitions
- Current index of the session.
 - Indices of disabled validators.
 - The owner of a key. The key is the
KeyTypeId+ the encoded key. - ModuleDeprecatedType alias to
Pallet, to be used byconstruct_runtime. - The next session keys for a validator.
 - True if the underlying economic identities or weighting behind the validators has changed in the queued validator set.
 - The queued keys for the next session. When the next session begins, these keys will be used to determine the validator’s session keys.
 - The current set of validators.
