Struct sc_consensus_slots::BackoffAuthoringOnFinalizedHeadLagging

pub struct BackoffAuthoringOnFinalizedHeadLagging<N> {
    pub max_interval: N,
    pub unfinalized_slack: N,
    pub authoring_bias: N,
}

A simple default strategy for how to decide backing off authoring blocks if the number of unfinalized blocks grows too large.

Fields

max_interval: N

The max interval to backoff when authoring blocks, regardless of delay in finality.

unfinalized_slack: N

The number of unfinalized blocks allowed before starting to consider to backoff authoring blocks. Note that depending on the value for authoring_bias, there might still be an additional wait until block authorship starts getting declined.

authoring_bias: N

Scales the backoff rate. A higher value effectively means we backoff slower, taking longer time to reach the maximum backoff as the unfinalized head of chain grows.

Trait Implementations

impl<N> BackoffAuthoringBlocksStrategy<N> for BackoffAuthoringOnFinalizedHeadLagging<N>where N: BaseArithmetic + Copy,

fn should_backoff( &self, chain_head_number: N, chain_head_slot: Slot, finalized_number: N, slot_now: Slot, logging_target: &str ) -> bool

Returns true if we should backoff authoring new blocks.

impl<N: Clone> Clone for BackoffAuthoringOnFinalizedHeadLagging<N>

fn clone(&self) -> BackoffAuthoringOnFinalizedHeadLagging<N>

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<N: BaseArithmetic> Default for BackoffAuthoringOnFinalizedHeadLagging<N>

These parameters is supposed to be some form of sensible defaults.

fn default() -> Self

Returns the “default value” for a type.
