# wasmd-client
|
||
|
|
|
||
|
|
`wasmd-client` is a Rust library that provides a trait and implementation for interacting with CosmWasm-enabled blockchains, specifically designed for use with the `wasmd` daemon.
|
||
|
|
|
||
|
|
## Features
|
||
|
|
|
||
|
|
- Query smart contracts
|
||
|
|
- Execute transactions on smart contracts
|
||
|
|
- Deploy new smart contracts
|
||
|
|
- Query transaction details
|
||
|
|
|
||
|
|
## Installation
|
||
|
|
|
||
|
|
Add this to your `Cargo.toml`:
|
||
|
|
|
||
|
|
```toml
|
||
|
|
[dependencies]
|
||
|
|
wasmd-client = { path = "../packages/wasmd-client" }
|
||
|
|
```
|
||
|
|
|
||
|
|
## Usage
|
||
|
|
|
||
|
|
The main interface is provided through the `WasmdClient` trait:
|
||
|
|
|
||
|
|
|
||
|
|
```9:44:cosmwasm/packages/wasmd-client/src/lib.rs
|
||
|
|
pub trait WasmdClient {
|
||
|
|
type Address: AsRef<str>;
|
||
|
|
type Query: ToString;
|
||
|
|
type RawQuery: ToHex;
|
||
|
|
type ChainId: AsRef<str>;
|
||
|
|
type Error;
|
||
|
|
|
||
|
|
fn query_smart<R: DeserializeOwned>(
|
||
|
|
&self,
|
||
|
|
contract: &Self::Address,
|
||
|
|
query: Self::Query,
|
||
|
|
) -> Result<R, Self::Error>;
|
||
|
|
|
||
|
|
fn query_raw<R: DeserializeOwned + Default>(
|
||
|
|
&self,
|
||
|
|
contract: &Self::Address,
|
||
|
|
query: Self::RawQuery,
|
||
|
|
) -> Result<R, Self::Error>;
|
||
|
|
|
||
|
|
fn query_tx<R: DeserializeOwned + Default>(&self, txhash: &str) -> Result<R, Self::Error>;
|
||
|
|
|
||
|
|
fn tx_execute<M: ToString>(
|
||
|
|
&self,
|
||
|
|
contract: &Self::Address,
|
||
|
|
chain_id: &Id,
|
||
|
|
gas: u64,
|
||
|
|
sender: &str,
|
||
|
|
msg: M,
|
||
|
|
) -> Result<String, Self::Error>;
|
||
|
|
|
||
|
|
fn deploy<M: ToString>(
|
||
|
|
&self,
|
||
|
|
chain_id: &Id,
|
||
|
|
sender: &str, // what should this type be
|
||
|
|
wasm_path: M,
|
||
|
|
) -> Result<String, Self::Error>;
|
||
|
|
```
|
||
|
|
|
||
|
|
|
||
|
|
To use the client, implement this trait for your specific needs or use the provided implementation.

|
|
||
|
|
### Querying a Smart Contract
|
||
|
|
|
||
|
|
```rust
|
||
|
|
let result: MyResponseType = client.query_smart(&contract_address, query_msg)?;
|
||
|
|
```
|
||
|
|
|
||
|
|
### Executing a Transaction
|
||
|
|
|
||
|
|
```rust
|
||
|
|
let tx_hash = client.tx_execute(&contract_address, &chain_id, gas, &sender, execute_msg)?;
|
||
|
|
```
|
||
|
|
|
||
|
|
### Deploying a New Contract
|
||
|
|
|
||
|
|
```rust
|
||
|
|
let contract_address = client.deploy(&chain_id, &sender, wasm_file_path)?;
|
||
|
|
```
|
||
|
|
|
||
|
|
### Querying a Transaction
|
||
|
|
|
||
|
|
```rust
|
||
|
|
let tx_result: MyTxResultType = client.query_tx(&tx_hash)?;
|
||
|
|
```
|
||
|
|
|
||
|
|
## Error Handling
|
||
|
|
|
||
|
|
The `WasmdClient` trait uses an associated `Error` type, allowing for flexible error handling depending on the specific implementation.
|
||
|
|
|
||
|
|
## Development
|
||
|
|
|
||
|
|
To run tests:
|
||
|
|
|
||
|
|
```sh
|
||
|
|
cargo test
|
||
|
|
```
