Fetch All Closed Events - Cairo Contract

[mubarak23]

Create a Smart Contract function that fetch All Closed Events, the function should return Array of EventDetails

Add the interface function inside IEvent.cairo

fn fetch_all_closed_events(self: @TContractState) -> Array<EventDetails>;

write your function inside chaineventts contract. (event/chaineventts.cairo)

Acceptance criteria

Function return Array containing all closed events.
write test for the function

Application for Fetching All Closed Events - Cairo Contract

Hi @mubarak23,

I am interested in implementing this feature to fetch all closed events in the chaineventts.cairo contract. I have experience working with Cairo and Starknet, and I will ensure the function is optimized for efficiency.

Implementation Plan

1. Define the Interface Function
   • Add the following function inside IEvent.cairo:

     fn fetch_all_closed_events(self: @TContractState) -> Array<EventDetails>;

2. Implement the Function in chaineventts.cairo
   • Retrieve stored event data and filter out only closed events.
   • Return an array of EventDetails for the closed events.
3. Write Test Cases
   • Ensure the function correctly returns only closed events.
   • Test edge cases, including scenarios where there are no closed events.

ETA

I estimate completing this within 12 hours, ensuring proper functionality and comprehensive test coverage.

Looking forward to your approval! 🚀

Best,
Jagadeesh B.

I'd like to handle this task.
HI Im Akinshola Akinniyi, a fullstack web3 developer, im conversant with creating smart contracts and I'm confident I can handle this task,
I will create the function to fetch all closed events, following the already provided standard by the other functions, create event for it and assert that the function is working as expected, please assign this task to me

I will fetch all closed events

I am from Starknet Winter Hackathon

I have great experience with Cairo, and am familiar with this codebase. I would love to work on this, fetch the closed events and write a detailed test.

ETA: 8 hours prompt.

I’d like to create the smart contract function to fetch all closed events, returning an array of EventDetails. This includes adding the interface function to IEvent.cairo, implementing it in chaineventts.cairo, and writing tests to ensure functionality and reliability.

Hi there! 👋

I’m a software engineer and blockchain developer with experience in Cairo, Solidity, JavaScript, TypeScript, and Rust. I’m excited to make my first contribution on OnlyDust and would love to take on this issue!

My approach

To implement the fetch_all_closed_events function, I will first add the interface function fn fetch_all_closed_events(self: @TContractState) -> Array; to IEvent.cairo to define the expected behavior. Next, I will write the function logic inside the chaineventts.cairo contract. The function will iterate through all events using the event_counts variable, check if each event’s is_closed flag is true, and append closed events to an array to be returned. To ensure correctness, I will write comprehensive tests that cover scenarios such as no closed events, all events closed, and mixed open/closed events. This approach ensures the function meets the acceptance criteria and integrates seamlessly with the existing contract.
