Extension trait providing read access to staking data.

Provided Methods

fn get_stake_params<'life0, 'async_trait>( &'life0 self, ) -> Pin<Box<dyn Future<Output = Result<StakeParameters>> + Send + 'async_trait>>

where Self: Sync + 'async_trait, 'life0: 'async_trait,

Gets the stake parameters from the JMT.

fn signed_blocks_window_len<'life0, 'async_trait>( &'life0 self, ) -> Pin<Box<dyn Future<Output = Result<u64>> + Send + 'async_trait>>

where Self: Sync + 'async_trait, 'life0: 'async_trait,

fn missed_blocks_maximum<'life0, 'async_trait>( &'life0 self, ) -> Pin<Box<dyn Future<Output = Result<u64>> + Send + 'async_trait>>

where Self: Sync + 'async_trait, 'life0: 'async_trait,

fn get_delegation_changes_tally(&self) -> DelegationChanges

Delegation changes accumulated over the course of this block, to be persisted at the end of the block for processing at the end of the next epoch.

fn get_current_base_rate<'life0, 'async_trait>( &'life0 self, ) -> Pin<Box<dyn Future<Output = Result<BaseRateData>> + Send + 'async_trait>>

where Self: Sync + 'async_trait, 'life0: 'async_trait,

fn get_previous_base_rate(&self) -> Option<BaseRateData>

fn get_funding_queue( &self, ) -> Option<Vec<(IdentityKey, FundingStreams, Amount)>>

Returns the funding queue from object storage (end-epoch).

fn get_delegation_changes<'life0, 'async_trait>( &'life0 self, height: Height, ) -> Pin<Box<dyn Future<Output = Result<DelegationChanges>> + Send + 'async_trait>>

where Self: Sync + 'async_trait, 'life0: 'async_trait,

Returns the DelegationChanges at the given Height.

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.
