Crate sp_inherents
source · [−]Expand description
Provides types and traits for creating and checking inherents.
Each inherent is added to a produced block. Each runtime decides on which inherents it
wants to attach to its blocks. All data that is required for the runtime to create the inherents
is stored in the InherentData. This InherentData is constructed by the node and given to
the runtime.
Types that provide data for inherents, should implement InherentDataProvider and need to be
registered at InherentDataProviders.
In the runtime, modules need to implement ProvideInherent when they can create and/or check
inherents. By implementing ProvideInherent, a module is not enforced to create an inherent.
A module can also just check given inherents. For using a module as inherent provider, it needs
to be registered by the construct_runtime! macro. The macro documentation gives more
information on how that is done.
Structs
The result of checking inherents.
An error that can occur within the inherent data system.
Inherent data to include in a block.
All InherentData providers.
Auxiliary to make any given error resolve to is_fatal_error() == true.
Traits
Did we encounter a fatal error while checking an inherent?
A pallet that provides or verifies an inherent extrinsic.
Something that provides inherent data.
Type Definitions
An identifier for an inherent.
