Slow Debug Recompilations

If you experience slow compile times when iterating with lots of templates, you can compile Askama's derive macros with a higher optimization level. This can speed up recompilation times dramatically.

Add the following to Cargo.toml or .cargo/config.toml:

fn main() {
opt-level = 3

This may affect clean compile times in debug mode, but incremental compiles will be faster.
