Implementations

impl Header

pub fn timestamp(&self) -> Result<Timestamp, TendermintClientError>

pub fn height(&self) -> Height

pub fn as_untrusted_block_state(&self) -> UntrustedBlockState<'_>

pub fn as_trusted_block_state<'a>( &'a self, chain_id: &'a Id, header_time: Time, next_validators_hash: Hash, ) -> Result<TrustedBlockState<'a>, TendermintClientError>

pub fn verify_chain_id_version_matches_height( &self, chain_id: &ChainId, ) -> Result<(), TendermintClientError>

pub fn check_trusted_next_validator_set<H>( &self, trusted_next_validator_hash: &Hash, ) -> Result<(), ClientError>

where H: MerkleHash + Sha256 + Default,

header.trusted_next_validator_set was given to us by the relayer. Thus, we need to ensure that the relayer gave us the right set, i.e. by ensuring that it matches the hash we have stored on chain.

pub fn validate_basic<H>(&self) -> Result<(), TendermintClientError>

where H: MerkleHash + Sha256 + Default,

Checks if the fields of a given header are consistent with the trusted fields of this header.

Trait Implementations

impl Clone for Header

fn clone(&self) -> Header

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Header

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Header

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for Header

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

Formats the value using the given formatter.

impl From<Header> for Any

fn from(header: Header) -> Any

Converts to this type from the input type.

impl From<Header> for ConsensusState

fn from(header: Header) -> ConsensusState

Converts to this type from the input type.

impl From<Header> for Header

fn from(value: Header) -> Header

Converts to this type from the input type.
