Required Methods§

Source

fn best_root(&self) -> BlockRoot

Best block root

Source

fn best_header(&self) -> Block::Header

Best block header

Source

fn ancestor_header( &self, ancestor_block_number: BlockNumber, descendant_block_root: &BlockRoot, ) -> Option<Block::Header>

Get header of ancestor block number for descendant block root

Source

fn header(&self, block_root: &BlockRoot) -> Option<Block::Header>

Dyn Compatibility§

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
