Project Title: Rust Samples

One-liner: New Implementation of NCD.L1–samples using Rust and Near-sdk-rs

Project Summary: : Each NCD.L1–samples projects should have branches with the same contract implemented using other programming languages. I’m currently working in creating a “near-sdk-rs” version for each of the 10 samples.

Project Members: Lucas Lemos

Extra: Anyone good with rust or contracts wanting to help me finish this faster, contact me on discord On0n0k1#3800

Period: Jan 08 → Jan 31 (Brazil)

Week 2:

  • “Thanks” repository, finished. link: https://github.com/On0n0k1/NCD.L1.sample--thanks/tree/near-sdk-rs
  • “Library” repository, finished. https://github.com/On0n0k1/NCD.L1.sample--library/tree/near-sdk-rs
  • “Promises” repository. Unfinished, didn’t send a pull request yet. Link: https://github.com/On0n0k1/temporary_sample_promises

Week 3:

  • Art Demo repository, finished. Link: https://github.com/On0n0k1/NCD.L1.sample--art-demo/tree/near-sdk-rs
  • Meme Museum repository has 2 contracts, meme and museum . Built the workspace for the contracts. meme contract is finished and tested. museum contract code is implemented, but unit tests still to be implemented. Link: https://github.com/On0n0k1/NCD.L1.sample--meme-museum/tree/near-sdk-rs
  • Currently, creating tests in rust for near-sdk-rs usually take 3 to 5 lines of code for each function call. Therefore, I started implementing a macro that would allow developers to run each function test in a single line of code, using the least amount of arguments needed. A macro like that would simplify testing and make it easier for learners to create their first rust contracts. After implementing the macro, will turn it into a unique module and send a pull request for near-sdk-rs. Then finish implementing museum unit tests.

Week 4:

  • Studied macro_rules in rust.
  • Implemented the macro. Link: https://github.com/On0n0k1/near-sdk-rs/commit/cd833c592b8b7c89973e3340eea68e9eb6396067.
  • Tested the macro locally.
  • Implemented documentation.
  • Sent a pull request.
  • Back to implementing samples projects into rust now.
