Rust Terra Proto

Clients used to interact with Terra Blockchain from Rust. It can be used directly with CosmWasm smart contracts as for example on Alliance Hub or from an external blockchain API.

Usage in CosmWasm

Integrate terra-proto-rs into the Cargo.toml from your smart contract with default-features to false that way you avoid importing libraries that will make your smart contract fail:

terra-proto-rs = {version = "5.0.0", default-features = false}

Available models for CosmWasm

When building a smart contract you can use the following messages natively without having to parse the structs, just import and use them:

Example

Extracting and simplifying a code snippet the delegate function in Alliance Hub smart contract from Alliance Protocol:

fn alliance_delegate(
    deps: DepsMut,
    env: Env,
    info: MessageInfo,
    msg: AllianceDelegateMsg,
) -> Result<Response, ContractError> {
    let mut msgs: Vec<CosmosMsg<Empty>> = vec![];
    
    for delegation in msg.delegations {
        ///
        /// Using MsgDelegate from alliance
        ///
        let delegate_msg = MsgDelegate {
            amount: Some(Coin {
                denom: config.alliance_token_denom.clone(),
                amount: delegation.amount.to_string(),
            }),
            delegator_address: env.contract.address.to_string(),
            validator_address: delegation.validator.to_string(),
        };
        ///
        // Creating the Stargate message to be routed on the alliance module
        // from terras blockchain on Response::message
        ///
        msgs.push(CosmosMsg::Stargate {
            type_url: "/alliance.alliance.MsgDelegate".to_string(),
            value: Binary::from(delegate_msg.encode_to_vec()),
        });
    }

    Ok(Response::new()
