Apache AGE (Rust Driver)

What is Apache AGE

AGE is opensource backend for postgres, that allows user to perform graph related operations on postgres. You can read about it on the official website

This repository will be eventually merged into the age repository. The status of the work needed for PR can be found in the special issue within AGE issue tracker

Important note

This library is just a wrapper around existing postgres libraries. Connection parameters, methods etc. are indentical (unless noted) as in the postgres and tokio-postgres crates.

Driver usage

More examples can be find in documentation (link below)

use apache_age::{NoTls, AgType};
use apache_age::sync::{AgeClient, Client}; 
use serde::{Deserialize, Serialize};

let mut client = Client::connect_age(
  "host=localhost user=postgres password=passwd port=8081",
  NoTls
).unwrap();

client.create_graph("my_apache_graph");

#[derive(Debug, Serialize, Deserialize, Clone)]
struct Person {
    pub name: String,
    pub surname: String,
}

match client.query_cypher::<()>(
    "my_apache_graph",
    "MATCH (n: Person) WHERE n.name = 'Alfred' RETURN {name: n.name, surname: n.surname}",
    None,
) {
    Ok(rows) => {
        let x: AgType<Person> = rows[0].get(0);
        // do whatever you need
    }
    Err(e) => {
        // handle error
    }
}

client.drop_graph("my_apache_graph");
