Struct CosmosChainClient 

pub struct CosmosChainClient { /* private fields */ }

Cosmos implementation of ChainClient.

Translates ChainClient methods into Tendermint JSON-RPC calls:

• get_head_height() → status → sync_info.latest_block_height
• get_block_by_height(h) → block with height=h
• health_check() → health

Implementations

impl CosmosChainClient

pub fn new( transport: Arc<dyn RpcTransport>, chain_id: impl Into<String>, ) -> Self

Create a Cosmos chain client.

Trait Implementations

impl ChainClient for CosmosChainClient

fn get_head_height<'life0, 'async_trait>( &'life0 self, ) -> Pin<Box<dyn Future<Output = Result<u64, TransportError>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

Get the current head height (block number / slot / checkpoint).

fn get_block_by_height<'life0, 'async_trait>( &'life0 self, height: u64, ) -> Pin<Box<dyn Future<Output = Result<Option<ChainBlock>, TransportError>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

Get a block by its height.

fn chain_id(&self) -> &str

Return the chain identifier (e.g. "1" for Ethereum mainnet, "mainnet-beta" for Solana).

fn chain_family(&self) -> &str

Return the chain family name (e.g. "evm", "solana", "cosmos").

fn health_check<'life0, 'async_trait>( &'life0 self, ) -> Pin<Box<dyn Future<Output = Result<bool, TransportError>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

Perform a health check against the underlying transport.
