}

Something which fulfills the abstract idea of a Tetcore block. It has types for Extrinsic pieces of information as well as a Header.

You can get an iterator over each of the extrinsics and retrieve the header.

Required Associated Types

type Extrinsic: Member + Codec + Extrinsic + MaybeSerialize + MaybeMallocSizeOf

Type for extrinsics.

type Header: Header<Hash = Self::Hash> + MaybeMallocSizeOf

Header type.

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

Block hash type.

Required Methods

fn header(&self) -> &Self::Header

Returns a reference to the header.

fn extrinsics(&self) -> &[Self::Extrinsic]

Returns a reference to the list of extrinsics.

fn deconstruct(self) -> (Self::Header, Vec<Self::Extrinsic>)

Split the block into header and list of extrinsics.

fn new(header: Self::Header, extrinsics: Vec<Self::Extrinsic>) -> Self

Creates new block from header and extrinsics.

fn encode_from(header: &Self::Header, extrinsics: &[Self::Extrinsic]) -> Vec<u8>

Creates an encoded block from the given header and extrinsics without requiring the creation of an instance.

Provided Methods

fn hash(&self) -> Self::Hash

Returns the hash of the block.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
