    pub fn hash(&self) -> Self::Hash { ... }
}

Something which fulfills the abstract idea of a Substrate 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.

Associated Types

type Extrinsic: Member + Codec + Extrinsic + MaybeSerialize + MaybeMallocSizeOf[src]

Required methods

pub fn header(&self) -> &Self::Header[src]

Returns a reference to the header.

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

Notable traits for &'_ [u8]

impl<'_> Read for &'_ [u8]impl<'_> Write for &'_ mut [u8]
[src]

Returns a reference to the list of extrinsics.

pub fn deconstruct(self) -> (Self::Header, Vec<Self::Extrinsic>)[src]

Split the block into header and list of extrinsics.

pub fn new(header: Self::Header, extrinsics: Vec<Self::Extrinsic>) -> Self[src]

Creates new block from header and extrinsics.

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

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