- This is a breaking change. - The new error type had to be made public, otherwise `Uniform` could not be extended for user-defined types by implementing `UniformSampler`. - `rand_distr` was updated accordingly. - Also forbid unsafe code for crates where none is used. Fixes rust-random#1195, rust-random#1211.

There was a problem hiding this comment.
There's not really a reason users shouldn't call these directly now (IIRC we used to have an assert in Uniform::new), though Uniform::new is probably still the more convenient API.

I'll try to look into it later this week. |
