Crate ipfs_api

Expand description

Rust library for connecting to the IPFS HTTP API using Hyper/Actix.

Usage

Using Hyper

To use the Hyper backend, declare:

[dependencies]
ipfs-api-backend-hyper = "0.6"

You can specify either with-hyper-rustls or with-hyper-tls (mutually exclusive) feature for TLS support.

Using Actix

To use the Actix backend, declare:

[dependencies]
ipfs-api-backend-actix = "0.7"

Builder Pattern

With either the Hyper or Actix backend, you can specify the with-builder feature to enable a builder pattern to use when building requests.

Usage (DEPRECATED)

[dependencies]
ipfs-api = "0.17.0"

Feature Flags (DEPRECATED)

You can use actix-web as a backend instead of hyper.

[dependencies]
ipfs-api = { version = "0.17.0", features = ["with-actix"], default-features = false }

You also have the option of using rustls instead of native tls:

[dependencies]
ipfs-api = { version = "0.17.0", features = ["with-hyper-rustls"], default-features = false }

To enable the builder pattern (default) use the with-builder feature:

[dependencies]
ipfs-api = { version = "0.17.0", features = ["with-hyper-rustls", "with-builder"], default-features = false }

Examples

Writing a file to IPFS

With Hyper

use ipfs_api::{IpfsApi, IpfsClient};
use std::io::Cursor;

#[tokio::main]
async fn main() {
    let client = IpfsClient::default();
    let data = Cursor::new("Hello World!");

    match client.add(data).await {
        Ok(res) => println!("{}", res.hash),
        Err(e) => eprintln!("error adding file: {}", e)
    }
}

With Actix

use ipfs_api::{IpfsApi, IpfsClient};
use std::io::Cursor;

#[actix_rt::main]
async fn main() {
    let client = IpfsClient::default();
    let data = Cursor::new("Hello World!");

    match client.add(data).await {
        Ok(res) => println!("{}", res.hash),
        Err(e) => eprintln!("error adding file: {}", e)
    }
}

Reading a file from IPFS

With Hyper

use futures::TryStreamExt;
use ipfs_api::{IpfsApi, IpfsClient};
use std::io::{self, Write};

#[tokio::main]
async fn main() {
    let client = IpfsClient::default();

    match client
        .get("/test/file.json")
        .map_ok(|chunk| chunk.to_vec())
        .try_concat()
        .await
    {
        Ok(res) => {
            let out = io::stdout();
            let mut out = out.lock();

            out.write_all(&res).unwrap();
        }
        Err(e) => eprintln!("error getting file: {}", e)
    }
}

With Actix

use futures::TryStreamExt;
use ipfs_api::{IpfsApi, IpfsClient};
use std::io::{self, Write};

#[actix_rt::main]
async fn main() {
    let client = IpfsClient::default();

    match client
        .get("/test/file.json")
        .map_ok(|chunk| chunk.to_vec())
        .try_concat()
        .await
    {
        Ok(res) => {
            let out = io::stdout();
            let mut out = out.lock();

            out.write_all(&res).unwrap();
        }
        Err(e) => eprintln!("error getting file: {}", e)
    }
}
