I'm following along the book "Writing An Interpreter In Go" by Thorsten Ball and "Writing a Compiler in Go" by Thorsten Ball implementing a toy language call Monkey.
I am using Rust instead of Go to help learn the language.

Use the following commands to generate flamegraphs with cargo flamegraph
cargo flamegraph --dev --bin=flamegraph --root -o tmp/flamegraph-vm.svg -- --engine=vm
cargo flamegraph --dev --bin=flamegraph --root -o tmp/flamegraph-eval.svg -- --engine=eval
