# The first thing we’ll do is enable link-time optimization (LTO). 
# It’s a kind of whole-program or inter-module optimization as it runs as the very last step when linking the different parts of your binary together.
# You can think of it as allowing better inlining across dependency boundaries (but it’s of course more complicated that that).
# Rust can use multiple linker flavors, and the one we want is “optimize across all crates”, which is called “fat”.
lto = "fat"

# Next up is a similar topic.
# To speed up compile times, Rust tries to split your crates into small chunks and compile as many in parallel as possible.
# The downside is that there’s less opportunities for the compiler to optimize code across these chunks.
# So, let’s tell it to do one chunk per crate
codegen-units = 1

# Now we get into some of the more unsafe options.
# Remember how Rust by default uses stack unwinding (on the most common platforms)?
# That costs performance! Let’s skip stack traces and the ability to catch panics for reduced code size and better cache usage
panic = "abort"
