ethportal-api

Warning! This crate is experimental! Do not rely on it in a production setting.

This crate contains definitions for various Portal Network JSON-RPC APIs using jsonrpsee framework.

Client usage example

Enable client feature of ethportal-api crate.

use ethportal_api::jsonrpsee::http_client::HttpClientBuilder;
use ethportal_api::{
    HistoryContentValue, HistoryContentKey, HistoryNetworkApiClient, Web3ApiClient,
};

#[tokio::main]
async fn main() {
    // Connect to a local node JSON-RPC
    let client = HttpClientBuilder::default()
        .build("http://localhost:8545")
        .unwrap();

    // Call web3_clientVersion endpoint
    let client_version = client.client_version().await.unwrap();
    println!("Current client version is {client_version}");

Types

A variety of types are published in the types module. For now, types go into this module if either 1) they are used by multiple crates, or 2) it's part of the ethportal-api type signatures. Importantly, ethportal-api shouldn't have andy dependencies on other crates in the workspace. It's a goal to be able to publish ethportal-api without also publishing any other supporting crates.

Especially during this experimental period, the types are subject to change, as many of them are used internally by trin. When ethportal-api becomes production-ready, the types will follow semantic versioning as usual: any incompatible change will be introduced with a major version increase.

Utilities used throughout trin are still generally kept in trin-utils, unless they are used by ethportal-api. Then they are published into ethportal-api, like the hex utilities.
