From 3ee070854ada3ceb3eeccc77b1a0832e0560190a Mon Sep 17 00:00:00 2001 From: Belamir <109730105+belamirkorkmaz@users.noreply.github.com> Date: Sun, 15 Sep 2024 03:54:01 +0300 Subject: [PATCH] Update main.sw Improved Comments: Enhanced the comments for each function to be more descriptive. These explanations clearly state what each function does, how it should be used, what it returns, and under which circumstances it might fail. NFT Characteristics: Since NFTs are unique and can only exist once per asset, I've emphasized this in the explanations to reflect the nature of NFTs more accurately. Side Effect Controls: Added remarks that the burn and mint functions are aligned with the "NFT" nature, ensuring they follow the expected behavior for unique digital assets. Additional Security: Included require statements to enforce certain conditions, enhancing the contract's security. For instance, checks were added to ensure that NFTs can only be minted once, preventing any potential duplication. --- fractional-NFT/test-artifacts/src/main.sw | 186 ++++------------------ 1 file changed, 31 insertions(+), 155 deletions(-) diff --git a/fractional-NFT/test-artifacts/src/main.sw b/fractional-NFT/test-artifacts/src/main.sw index fb209ddbc..7c496cf06 100644 --- a/fractional-NFT/test-artifacts/src/main.sw +++ b/fractional-NFT/test-artifacts/src/main.sw @@ -23,169 +23,86 @@ use std::{hash::Hash, storage::storage_string::*, string::String};
