Example

Via Builder

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

#[tokio::main]
async fn main() -> Result<()> {
    let mut builder = NebulaGraph::default();
    builder.root("/");
    builder.host("127.0.0.1");
    builder.port(9669);
    builder.space("your_space");
    builder.tag("your_tag");
    // key field type in the table should be compatible with Rust's &str like text
    builder.key_field("key");
    // value field type in the table should be compatible with Rust's Vec<u8> like bytea
    builder.value_field("value");

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