Description
I tried this code (what cargo new --lib
generates):
pub fn add(left: u64, right: u64) -> u64 {
left + right
}
#[cfg(test)]
mod tests {
use super::*;
#[test]
fn it_works() {
let result = add(2, 2);
assert_eq!(result, 4);
}
}
I expected both rustdoc
and rustdoc --test
to behave identically with respect to -Zcrate-attr
, but:
% rustdoc +nightly src/lib.rs -Zcrate-attr='feature(strict_provenance_lints)' -Wfuzzy_provenance_casts
% echo $?
0
% rustdoc +nightly --test src/lib.rs -Zcrate-attr='feature(strict_provenance_lints)' -Wfuzzy_provenance_casts
