This is the full list of lints, all other crates have some subset of this. Only a few allow unsafe_code, I will list them:

cuprate_helper uses unsafe 1 time here.

cuprate_blockchain uses unsafe for UnsafeSendable.

cuprate_database uses unsafe for:
pub unsafe trait DatabaseRoheed
The #[expect]s everywhere may seem a bit messy although it does mean the rest of cuprate_database is known not to use unsafe, this may be worth it.

What
#![forbid]lints for all crates where applicableunsafe_code = "deny"toCargo.tomlWhy
Allows us to uphold certain static invariants within crates, the most useful one being
unsafe_code.Within the crates that use
unsafe, only a small portion of the crate needsunsafe. Notating the files that need it with#[expect(unsafe_code)]allows the rest of the crate to be known safe (at least the keyword, obviously usingunsafeincorrectly can cause safe code to be unsafe).I.e. it defines and restricts the
unsafeinterface to certain portions of the crate.
