Struct sc_consensus_slots::SlotDuration

pub struct SlotDuration<T>(_);

A slot duration. Create with get_or_compute.

Implementations

impl<T: Clone + Send + Sync + 'static> SlotDuration<T>

pub fn get_or_compute<B: BlockT, C, CB>(client: &C, cb: CB) -> Result<Self> where
    C: AuxStore + UsageProvider<B>,
    C: ProvideRuntimeApi<B>,
    CB: FnOnce(ApiRef<'_, C::Api>, &BlockId<B>) -> Result<T>,
    T: SlotData + Encode + Decode + Debug, 

Either fetch the slot duration from disk or compute it from the genesis state.

slot_key is marked as 'static, as it should really be a compile-time constant.

pub fn get(&self) -> T

Returns slot data value.
