Via Builder

use anyhow::Result;
use opendal::services::Ipfs;
use opendal::Operator;

#[tokio::main]
async fn main() -> Result<()> {
    // create backend builder
    let mut builder = Ipfs::default()
        // set the endpoint for OpenDAL
        .endpoint("https://ipfs.io")
        // set the root for OpenDAL
        .root("/ipfs/QmPpCt1aYGb9JWJRmXRUnmJtVgeFFTJGzWFYEEX7bo9zGJ");

    let op: Operator = Operator::new(builder)?.finish();

    Ok(())
}
