System configuration trait. Implemented by runtime.

Associated Types

The basic call filter to use in Origin. All origins are built with this filter as base, except Root.

Block & extrinsics weights: base values and limits.

The maximum length of a block (in bytes).

The Origin type used by dispatchable calls.

The aggregated Call type.

Account index (aka nonce) type. This stores the number of previous transactions associated with a sender account.

The block number type used by the runtime.

The output of the Hashing function.

The hashing system (algorithm) being used in the runtime (e.g. Blake2).

The user account identifier type for the runtime.

Converting trait to take a source type and convert to AccountId.

Used to define the type and conversion mechanism for referencing accounts in transactions. It’s perfectly reasonable for this to be an identity conversion (with the source type being AccountId), but other pallets (e.g. Indices pallet) may provide more functional/efficient alternatives.

The block header.

The aggregated event type of the runtime.

Maximum number of block number to block hash mappings to keep (oldest pruned first).

The weight of runtime database operations the runtime can invoke.

Get the chain’s current version.

Provides information about the pallet setup in the runtime.

Expects the PalletInfo type that is being generated by construct_runtime! in the runtime.

For tests it is okay to use () as type, however it will provide “useless” data.

Data to be associated with an account (other than nonce/transaction counter, which this pallet does regardless).

Handler for when a new account has just been created.

A function that is invoked when an account has been determined to be dead.

All resources should be cleaned up associated with the given account.

The designated SS85 prefix of this chain.

This replaces the “ss58Format” property declared in the chain spec. Reason is that the runtime should know about the prefix in order to make use of it as an identifier of the chain.

What to do if the user wants the code set to something. Just use () unless you are in cumulus.
