Terra Binding for CosmWasm Contracts

如何使用查询器

use cosmwasm_std::Coin;
use terra_bindings::TerraQuerier;

let res: Coin = TerraQuerier::new(&deps.querier).query_swap(offer.clone(), ask)?;

如何使用消息创建器

use cosmwasm_std::CosmosMsg;
use terra_bindings::{create_swap_msg, TerraMsgWrapper};

let msg: CosmosMsg<TerraMsgWrapper> = create_swap_msg(contract_addr, offer_coin, ask_denom);
