This PR removes sp-std crate from substrate/primitives sub-directories. For now crates that have `pub use` of sp-std or export macros that would necessitate users of the macros to `extern crate alloc` have been excluded from this PR. There should be no breaking changes in this PR. --------- Co-authored-by: Koute <koute@users.noreply.github.com>
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.
