Struct jormungandr::blockcfg::Multiverse

pub struct Multiverse<State> {
    states_by_hash: HashMap<Hash, GcEntry<State>, RandomState>,
    states_by_chain_length: BTreeMap<ChainLength, HashSet<Hash, RandomState>, Global>,
}

Fields

states_by_hash: HashMap<Hash, GcEntry<State>, RandomState>

states_by_chain_length: BTreeMap<ChainLength, HashSet<Hash, RandomState>, Global>

Implementations

impl<State> Multiverse<State>

pub fn new() -> Multiverse<State>

pub fn get(&self, k: &Hash) -> Option<Arc<State, Global>>

pub fn get_ref(&self, k: &Hash) -> Option<Ref<State>>

pub fn nr_states(&self) -> usize

Return the number of states stored in memory.

pub fn insert( &mut self, chain_length: ChainLength, k: Hash, st: State ) -> Ref<State>

Add a state to the multiverse. Return a Ref object that pins the state in memory.

pub fn gc(&mut self, cut_to_depth: u32)

Once the state are old in the timeline, they are less and less likely to be used anymore, so we leave a gap between different version that gets bigger and bigger

Arguments

cut_to_depth - the depth from starting which branches would be removed.

impl Multiverse<Ledger>

pub fn add(&mut self, k: Hash, st: Ledger) -> Ref<Ledger>

Add a state to the multiverse. Return a Ref object that pins the state into memory.

Trait Implementations

impl<S> Default for Multiverse<S>

fn default() -> Multiverse<S>

Returns the “default value” for a type.
