New protocol storage extension for data that is not part of the legacy HotShot storage trait.

Required Methods

fn append_high_qc2<'life0, 'async_trait>( &'life0 self, high_qc: Certificate1<T>, ) -> Pin<Box<dyn Future<Output = Result<()>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

Persist the locked QC, written before each phase-2 vote so the lock survives a restart instead of regressing to the decided-anchor QC.

fn load_high_qc2<'life0, 'async_trait>( &'life0 self, ) -> Pin<Box<dyn Future<Output = Result<Option<Certificate1<T>>>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

Load the persisted locked QC, if any.

fn append_boundary_qc2<'life0, 'async_trait>( &'life0 self, qc: Certificate1<T>, ) -> Pin<Box<dyn Future<Output = Result<()>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

Persist the own Certificate1 of the last block of an epoch, at the block’s own view.

A re-vote request and the next epoch’s first block name it, and nothing else carries it once the view has passed: without it a restarted node cannot lead either. Implementations keep the latest, ordered by epoch, then view, as a monotonic compare-and-set.

fn load_boundary_qc2<'life0, 'async_trait>( &'life0 self, ) -> Pin<Box<dyn Future<Output = Result<Option<Certificate1<T>>>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

Load the persisted boundary certificate, if any.

Dyn Compatibility

This trait is not dyn compatible.

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