Required Methods

fn store_candidate(&mut self, cm: Block) -> Result<()>

Candidate Storage

fn candidate(&self, hash: &[u8]) -> Result<Option<Block>>

fn candidate_by_iteration(&self, ch: &ConsensusHeader) -> Result<Option<Block>>

Fetches a candidate block by lookup key (prev_block_hash, iteration).

fn clear_candidates(&mut self) -> Result<()>

fn delete_candidate<F>(&mut self, closure: F) -> Result<()>

where F: FnOnce(u64) -> bool + Copy,

fn count_candidates(&self) -> usize

fn store_validation_result( &mut self, ch: &ConsensusHeader, vr: &ValidationResult, ) -> Result<()>

ValidationResult Storage

fn validation_result( &self, ch: &ConsensusHeader, ) -> Result<Option<ValidationResult>>

fn clear_validation_results(&mut self) -> Result<()>

fn delete_validation_results<F>(&mut self, closure: F) -> Result<()>

where F: FnOnce([u8; 32]) -> bool + Copy,

fn count_validation_results(&self) -> usize

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.
