pub struct ConsensusState { /* private fields */ }

Provides consensus state tree from the host.

Implementations

impl ConsensusState

pub fn new(height: u64, tree: Tree) -> Self

pub fn from_protocol(protocol: Arc<Protocol>, height: u64, root: Root) -> Self

Creates consensus state using host protocol.

pub fn height(&self) -> u64

Consensus layer height that this data is for.
