Benchmark extend_from_slice vs extend_with_chain

This project benchmarks two different approaches for extending a vector in Rust and calculates their SHA-256 hashes to ensure they produce the same output.

Functions Being Benchmarked

• extend_from_slice: Extends a vector using the extend_from_slice method.
• extend_with_chain: Extends a vector using chained iterators.

SHA-256 Verification

Both approaches are verified to produce the same output by calculating and comparing their SHA-256 hashes.

Building and Running Manual Benchmark from main Function

To build and run the manual benchmark from main.rs, follow these steps:

1. Build the Project in Release Mode:

   cargo build -p slice_vs_iter --release

   This command builds the slice_vs_iter package in release mode, optimizing the code for performance.

2. Run the Manual Benchmark:

   ./target/release/slice_vs_iter

   This runs the built executable for slice_vs_iter, which contains the manual benchmarking code.

Running Criterion Benchmarks

To run the benchmarks using Criterion, you can run all benchmarks in the slice_vs_iter package:

 cargo bench -p slice_vs_iter
