A Rust Client for HarperDB

Introduction

HarperDB is a SQL/NoSQL data management platform. It is fully indexed, doesn't duplicate data, and runs on any device- from the edge to the cloud.

It is built natively as a set of micro-services, making development and integration easy and seamless. HarperDB utilizes a single-endpoint for all operations. HarperDB’s RESTful nature makes it stateless, stable, and scalable.

Examples

Dependencies: toml [dependencies] tokio = { version = "0.2", features = ["full"] } serde_json = "1.0" Basic usage:

```rust use harperdbsdkrust::{ HarperConfig, Harper }; use harperdbsdkrust as harper; use serde::{Deserialize, Serialize}; use serde_json::{Value}; use std::{error::Error};

[macro_use]

extern crate serde_json;

[derive(Debug, Serialize, Deserialize)]

struct DogRecord { id: usize, name: String, age: Option, breed: Option, image: Option, createdtime: usize, updatedtime: usize, }

[tokio::main]

async fn main() -> Result<(), Box> { let config: HarperConfig = HarperConfig { url: "http://0.0.0.0:9925/", username: "HDB_ADMIN", password: "password", schema: "dev", };

let harper_client = new(config);

// Insert Record
let insert_option: harper::QueryOptions = harper::QueryOptions {
    table: "dog",
    schema: "dev",
    records:json!([{
        "id": 1,
        "name": "Incredible Metal Chair",
        "breed": "Mutt",
        "age": 4,
        "image": "http://lorempixel.com/640/480/nature"
    }]),
};
let result = harper_client.insert(insert_option).await?;

// Get Query Response
println!("{:#?}", result.status());

// Query Database
let result = harper_client.query("SELECT * FROM dev.dog limit 2",).await?;

let dog_record: Vec<DogRecord> = result.json().await?;
println!("{:#?}", dog_record);

// Get result as text
// let data = result.text().await?;
// println!("{:#?}", data);

} ```
