Required Associated Types

type Error: Error

type Header: Header

type Content: Fragment

Required Methods

fn apply_block<'a, I>(
    &self,
    header: &Self::Header,
    contents: I
) -> Result<Self, Self::Error> where
    I: IntoIterator<Item = &'a Self::Content>,
    Self::Content: 'a, 

yield a new block in the state

This will change the state in the sense that it acknowledge the creation of a new block in its internal state.

fn apply_contents<'a, I>(&self, contents: I) -> Result<Self, Self::Error> where
    I: IntoIterator<Item = &'a Self::Content>,
    Self::Content: 'a, 

apply new block contents. This modify the state in small steps however it does not acknowledge the creation of a new block
