How to build

cargo build --release

Performance

It takes about 0.07 ish to read all the supported files in an unmodded bg1ee game, into memory, without parsing them.

time cargo run -- <path to bgee dir>/chitin.key
0.07s user 0.58s system 99% cpu 0.655 total

you can analyze performance:

cargo install flamegraph
flamegraph -- target/release/post_infinity <path to chitin file>
