This looks fine to me, but I am not sure we need to specifically test that custom implementations do not overwrite the default backends.
Also, I have an alternative proposal. I think we can do the following:
// in lib.rs
cfg_if! {
if #[cfg(all(test, test_rdrand))] {
mod lazy;
#[path = "rdrand.rs"] mod imp;
} else if #[cfg(all(test, test_custom, feature = "custom"))] {
use custom as imp;
} else if #[cfg( ... ))] {
// ...
}
}
// in tests module:
register_custom_getrandom!(mock_rng);
#[cfg(not(all(feature = "custom", test_custom)))]
#[test]
fn mock_rng_is_not_used() {
// ..
}
This will eliminate the weird juggling around RDRAND and will allow us to test a custom implementation on standard Linux targets. Using cfg(test)
will ensure that the testing branches will not escape outside of this crate.

@newpavlov @briansmith PTAL. I moved the custom.rs tests back to being an integration test, so both supported and unsupported platforms are now tested without changing the

I agree that RDRAND has some weird juggling, but that's probably best left for discussion in #476 |

This makes a lot more sense to me. Just a couple comments.
This marks the `tests/custom.rs` test as requiring the `"custom"` feature. It also: - Simplifies the registered custom RNG - Makes sure the custom RNG _is not_ used on supported platforms - Makes sure the custom RNG _is_ used on unsupported platforms Signed-off-by: Joe Richey <[email protected]>
This moves the tests for the custom RNG registration into custom.rs. It also:
