Summary
Some type is flagged by Clippy as never used, though it is used in an internal trait implementation
Lint Name
dead_code
Reproducer
I tried this code:
clone zama-ai/concrete-fft@aeb75d4
run pre commit checks, runs a clippy check:
make pcc
faulty clippy invokation:
RUSTFLAGS="-C target-cpu=native" cargo "+nightly-2024-07-18" clippy --all-targets \
--features=serde -- --no-deps -D warnings
I saw this happen:
error: type alias `Plus2` is never used
--> src/nat.rs:26:10
|
26 | pub type Plus2<N> = Successor<Plus1<N>>;
| ^^^^^
|
= note: `-D dead-code` implied by `-D warnings`
= help: to override `-D warnings` add `#[allow(dead_code)]`
error: type alias `Plus3` is never used
--> src/nat.rs:27:10
|
27 | pub type Plus3<N> = Successor<Plus2<N>>;
| ^^^^^
error: type alias `Plus4` is never used
--> src/nat.rs:28:10
|
28 | pub type Plus4<N> = Successor<Plus3<N>>;
| ^^^^^
error: could not compile `concrete-fft` (lib) due to 3 previous errors
I expected to see this happen:
No warning/error for these types as they are used in e.g. https://github.com/zama-ai/concrete-fft/blob/aeb75d4b7c5cc6b3031bf5b9f4730961f3132fe5/src/dit16.rs#L823
