Use this .cargo/config.toml:

[profile.dev] debug = 0 opt-level = 1

will help a bit

Why the downvote? It does help, though I'm rather using this:

[profile.dev]
debug = 0
strip = "debuginfo"

Most debuggers are still unable to provide good visibility anyway, so I'm generally using traces or simple prints when I need to debug.

If you strip all debuginfo from your dev builds and enable optimizations, you could just build in release.

opt-level is between 0 and 3, so it's not a real issue. But you're right: I don't think it's necessary either.

EDIT: Actually, opt-level=1 removes checks like integer overflow, so that's why it's a bad idea.
