This is an experiment to evaluate Rust vs. Zig by writing a bytecode interpreter with GC in both languages and comparing them.

The interpreter implementation is from the Crafting Interpreters book.

I wrote a comprehensive summary of this experiment on my personal blog.

This is in the loxide folder.

To build it:

# in the root project directory
make rust

# inside the rust folder
cargo build --release

To run the tests:

cargo test

# Run with miri to check for undefined behaviour
cargo miri test

This is in the zlox folder.

To build it:

# in the root project directory
make zig

# inside the zlox folder
# run `zig build help` for options
zig build

To run the tests:

zig build test
zig-out/bin/zlox

The benchmarks folder contains the code ("*.lox" files) the two interpreters run and the results of the benchmarks. The results are run using hyperfine.
