Minimal Substrate-based chain representation that may be used from no_std environment.

Required Associated Types

type BlockNumber: Parameter + Member + MaybeSerializeDeserialize + Hash + Copy + Default + MaybeDisplay + AtLeast32BitUnsigned + FromStr + AsPrimitive<usize>

A type that fulfills the abstract idea of what a Substrate block number is.

type Hash: Parameter + Member + MaybeSerializeDeserialize + Hash + Ord + Copy + MaybeDisplay + Default + SimpleBitOps + AsRef<[u8]> + AsMut<[u8]>

A type that fulfills the abstract idea of what a Substrate hash is.

type Hasher: HashT<Output = Self::Hash>

A type that fulfills the abstract idea of what a Substrate hasher (a type that produces hashes) is.

type Header: Parameter + HeaderT<Number = Self::BlockNumber, Hash = Self::Hash> + MaybeSerializeDeserialize

A type that fulfills the abstract idea of what a Substrate header is.
