Usage

Add the following to your cargo dependencies:

lazerpay-rust-sdk = "0.1.1"

Next you get your test LAZERPAY_PUBLIC_KEY and LAZERPAY_SECRET_KEY from Lazerpay dashboard

Add those to a .env file at the root of your project. You can check .env.example for an example.

With that out of the way, you can use the API to make payments.

use lazerpay_rust_sdk::{utils, Customer, Lazerpay, PaymentConfig};

#[tokio::main]
async fn main() {
    let api = Lazerpay::new();

    let mut payment = api.create_payment(PaymentConfig {
        customer: Customer::new("Enoch", "[email protected]"),
        reference: utils::generate_unique_reference(),
        coin: "USDC".into(),
        amount: "1000".into(),
        currency: "USD".into(),
        accept_partial_payment: true,
    });

    dbg!(payment.send().await.unwrap());
    dbg!(payment.check_confirmation().await.unwrap());
}

And transfer funds using the transfer API.

use lazerpay_rust_sdk::{utils, Customer, Lazerpay, TransferConfig};

#[tokio::main]
async fn main() {
    let api = Lazerpay::new();

    let mut transfer = api.create_transfer(TransferConfig {
        recipient: "0x0000000000000000000000000000000000000000".into(),
        blockchain: "Binance Smart Chain".into(),
        coin: "USDC".into(),
        amount: 1000,
    });

    dbg!(transfer.send().await.unwrap());
}

Finally, you can use get information on supported coins and their rates.

use lazerpay_rust_sdk::Lazerpay;

#[tokio::main]
async fn main() {
    let api = Lazerpay::new();

    dbg!(api.get_rates("USD", "USDC").await.unwrap());
    dbg!(api.get_accepted_coins().await.unwrap());
}

and that's it.

Examples

You could also try out the examples in the project. For example, to run the payment example, run:

cargo run --example payment

  • API Change Proposal

    API Change Proposal

    Right now, Lazerpay Rust SDK looks so much like the node SDK. The issue with that is the library doesn't take full advantage of Rust's type safety all in the spirit of staying true to the official implementation. But node is not Rust. JavaScript is a weakly typed language.

    For the reasons stated above, I would like to propose a slightly different, more Rusty interface for the SDK. Specifying it in a way that doesn't diverge too much from the reference implementation.

    I think it will help with creating a more solid foundation for the project as Lazerpay grows its features.

    let lazerpay = Lazerpay::new()?; // Sets up API keys. Grabs details from .env.

let payment = lazerpay.create_payment(PaymentConfig { // Returns a payment object but doesn't send req.
    customer: Customer::new("Lagbaja Ajanaku", "[email protected]"),
    coin: Coin::USDC,
    currency: Currency::NGN,
    amount: 5_000,
    pk_address: "0x16227d60f7a0e586c66b005219dfc887d13c9531",
    reference: "Just sending some money your way",
    ..Default::default()
})?;

payment.send()?; // Sends payment req.

payment.check_confirmation()?; // Asks for confirmation.

payment.get_accepted_coins()?; // Get supported coins.

    Let me know what you think and if there is any edge case I'm missing.

  • Refactor API

    Refactor API

    • Adjust interface
    • Add response deserialisation structs
    • Introduce results
    • Document

    TODO:

    • [x] Fix the tests. (The failing tests seem to be from Lazerpay end)

    Closes https://github.com/Lord-sarcastic/lazerpay-rust-sdk/issues/13 Closes https://github.com/Lord-sarcastic/lazerpay-rust-sdk/issues/12

    Areas of Improvement:

    • Need to have a proper type for coin/currency amounts/values. Right now the types of TransferConfig amount and PaymentConfig amount are different because that's what the Lazerpay API expects. It is not ideal and I have not come up with a better approach yet. Might need to meet with the Lazerpay devs for that.

  • Results over Unwraps

    Results over Unwraps

    Might want to return Results instead of unwrapping. This puts error handling into the users hands and prevents unexpected and sometimes unwanted panics.

  • Rename Library to `lazerpay`

    Rename Library to `lazerpay`

    I think the library should just be renamed lazerpay or lazerpay-rs. lazerpay-rust-sdk is a mouthful. There is no need for the ...-rust-sdk namespacing since this rust version is only ever going to exist in crates-verse.

    It also helps with discoverability.

Releases(v0.1.1)

  • v0.1.1(Mar 1, 2022)

  • v0.1.0(Feb 28, 2022)

    The primordial release. Contains about 5 API integrations:

    • Initialize transaction
    • Verify transaction
    • Get all accepted coins
    • Transfer
    • Get rate

    Future releases would involve more strictness on the typings and an improved structure.
