chain-registry-interface (Rust)

Typed runtime access to the Cosmos chain-registry at runtime. This crate mirrors the official JSON schemas (no embedded data) and provides minimal helpers to fetch JSON from GitHub.

Key points:

• Types match schema fields exactly (serde rename where needed).
• Optional fields use Option.
• No caching or validation beyond JSON parsing.

Install (after publish):

[dependencies]
chain-registry-interface = "0.0.1"

Example

use chain_registry_interface::fetch_chain;

#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
    let chain = fetch_chain("osmosis").await?;
    println!("{}", chain.chain_name);
    Ok(())
}

Helpers

• fetch_chain(name) -> Chain
• fetch_asset_list(name) -> AssetList
• fetch_memo_keys(_) -> MemoKeys
• fetch_versions(name) -> Versions
• fetch_ibc_connection(a, b) -> IbcData from _IBC/-.json
