Implementations

impl ClientState

pub fn new( chain_id: ChainId, trust_level: TrustThreshold, trusting_period: Duration, unbonding_period: Duration, max_clock_drift: Duration, latest_height: Height, proof_specs: Vec<ProofSpec>, upgrade_path: Vec<String>, allow_update: AllowUpdate, frozen_height: Option<Height>, ) -> Result<ClientState, Error>

pub fn latest_height(&self) -> Height

pub fn is_frozen(&self) -> bool

returns a bool indicating if the client is frozen, i.e. if a frozen height is set.

pub fn expired(&self, elapsed: Duration) -> bool

pub fn with_header(self, h: Header) -> Result<ClientState, Error>

pub fn with_frozen_height(self, h: Height) -> ClientState

pub fn unfrozen(self) -> ClientState

pub fn refresh_time(&self) -> Option<Duration>

Get the refresh time to ensure the state does not expire

pub fn as_light_client_options(&self) -> Result<Options, Error>

Helper method to produce a [Options] struct for use in Tendermint-specific light client verification.

pub fn verify_delay_passed( current_time: Timestamp, current_height: Height, processed_time: Timestamp, processed_height: Height, delay_period_time: Duration, delay_period_blocks: u64, ) -> Result<(), Error>

Verify the time and height delays

pub fn verify_height(&self, height: Height) -> Result<(), Error>

Verify that the client is at a sufficient height and unfrozen at the given height

Trait Implementations

impl Clone for ClientState

fn clone(&self) -> ClientState

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ClientState

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ClientState

fn deserialize<__D>( __deserializer: __D, ) -> Result<ClientState, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl DomainType for ClientState

type Proto = Any

fn encode_to_vec(&self) -> Vec<u8>
