[][src]Module rdrand::changelog::r0_4_0

Breaking changes

Crate gained an enabled-by-default std feature. If you relied on rdrand being core-able change your dependency to appear as such:

rdrand = { version = "0.4", default-features = false }

This is done so that an advantage of the common feature detection functionality could be employed by users that are not constrained by core. This functionality is faster, caches the results and is shared between all users of the functionality.

For core usage the feature detection has also been improved and will not be done if e.g. crate is built with rdrand instructions enabled globally.
