fuzz target compile_parse_tree not working #161
Description
Project version
main
Project
fuzz
What happened?
I was running the fuzz target on my computer just for fun, after a simplicity bootcamp in Sao Paulo, and when executing the target:
cargo +nightly fuzz run compile_parse_tree
I got the following error:
$ cargo +nightly fuzz run compile_parse_tree
Compiling simplicityhl-fuzz v0.0.0 (/Users/lucasbalieiro/Projects/SimplicityHL/fuzz)
error[E0425]: cannot find function `to_commit_node` in module `named`

So, shouldn't this fuzz target with something like this (?):
