Implementations

impl LightClientBuilder<NoTrustedState, Sha256>

pub fn prod( peer_id: PeerId, rpc_client: HttpClient, light_store: Box<dyn LightStore>, options: Options, timeout: Option<Duration> ) -> Self

Initialize a builder for a production (non-mock) light client.

impl<H> LightClientBuilder<NoTrustedState, H>

where H: MerkleHash + Sha256 + Default,

pub fn custom( peer_id: PeerId, options: Options, light_store: Box<dyn LightStore>, io: Box<dyn Io>, clock: Box<dyn Clock>, verifier: Box<dyn Verifier>, scheduler: Box<dyn Scheduler>, predicates: Box<dyn VerificationPredicates<Sha256 = H>> ) -> Self

Initialize a builder for a custom light client, by providing all dependencies upfront.

pub fn trust_light_block( self, trusted_state: LightBlock ) -> Result<LightClientBuilder<HasTrustedState, H>, Error>

Set the given light block as the initial trusted state.

pub fn trust_from_store( self ) -> Result<LightClientBuilder<HasTrustedState, H>, Error>

Keep using the latest verified or trusted block in the light store. Such a block must exists otherwise this will fail.

pub fn trust_primary_at( self, trusted_height: Height, trusted_hash: Hash ) -> Result<LightClientBuilder<HasTrustedState, H>, Error>

Set the block from the primary peer at the given height as the trusted state.

impl<H> LightClientBuilder<HasTrustedState, H>

where H: MerkleHash + Sha256 + Default,

pub fn build(self) -> Instance

Build the light client Instance.
