Factom Rust API Client

Installation

Add to cargo.toml:

[dependencies]

factom = "^2"

Quickstart

use factom::*;
// Get current block height from open node
#[tokio::main]
async fn main() {
  //Create a re-usable client
  let client = Factom::open_node();
  // Call the heights function, handle the request result
  let response = factomd::heights(&client).await.expect("Network Request");
  assert!(response.result.leaderheight > 0);
}

Usage

See the examples folder for common workflows, or use cargo run --example to view all those you can run.

Using default settings

let client = Factom::new();

Using the open node

// factom-walletd is at `http://localhost:8089`
let client = Factom::open_node();

Using the testnet open node

// factom-walletd is located at: 'http://localhost:8089`
let client = Factom::testnet_node();

Custom factomd and factom-walletd locations

let factomd = "https://api.factomd.net/";
let factom_walletd = "http://192.168.1.42:18089";
let client = Factom::custom_node(factomd, factom_walletd)

Retrieve a Balance

let client = factom.testnet_node();
let testnet_address = "FA2jK2HcLnRdS94dEcU27rF3meoJfpUcZPSinpb7AwQvPRY6RL1Q";
let response = balance::factoid_balance(&client, testnet_address).await.unwrap();
// factoid balance returns factoshis, convert
let factoids = utils::factoshis_to_fct(response.result.balance);
println!("The testnet balance of {} is {} factoids", FCT_PUB, factoids);

Get Entry Data

let client = factom.testnet_node();
let hash = "97c4e7adce9ed277b62adfb9fb7a31ca4778181e49dcdfebca967102dd424fbc";
let response = entry::entry(hash).await.unwrap();
dbg!(response);

Runtime

This library re-exports the tokio runtime and executor by default, to disable this and use a different runtime modify your cargo.toml with a feature flag:

[dependencies]

factom = {version="^2", features="no-runtime"}

Testing

Most of the functions are covered by the test modules along with all the documentation examples. Beware that running cargo test with nocapture will produce a huge amount of output. For many of the tests to pass you will need to be running factom-walletd, any test transactions or addresses are cleaned up afterward.

See the testing readme for instructions.

Benchmarking

A criterion benching harness is provided, if gnuplot is installed it will also automatically generate plots for any benchmarks run, they can be found at <LIBRARY>/target/criterion/report/index.html. This can be used to test the performance of factomd, factom-walletd, network connections and the library functions themselves. See the benches folder readme for more information.

Fuzzing

A fuzzing suite is provided using the rust implementation of American Fuzzy Lop, with appropriate setup this can be used to fuzz both the Factom rust library along with a simulated Factom network and factom-walletd. See the fuzz folder readme for more information.
