Using helper functions
Helper functions simplify complex blockchain operations, enhancing code readability, reusability, and maintenance. In Rust-based blockchain development, functions such as get_transactions, get_prev_block_hash, and get_hash abstract away intricacies, enabling modular design and efficient debugging while focusing on high-level logic.
Let’s add some functions to the block.rs file that can help us work with blocks:
pub fn get_transactions(&self) -> &[Transaction] {
        self.transactions.as_slice()
    } This function helps us to get the list of transactions, but let’s break it down and see what’s happening here.
This function is defined on a Rust struct and returns a borrowed reference to a slice of Transaction objects:
pubindicates that this function can be called from outside the struct.fnis the keyword that’s used to define a function...
