Previous behavior can be regained with - `rng.gen_ascii_chars().take(n).collect()` -- {IsaacRng, Isaac64Rng, XorShiftRng}::new() have all been removed. These all - relied on being able to use an OSRng for seeding, but this is no longer - available in librand (where these types are defined). To retain the same - functionality, these types now implement the `Rand` trait so they can be - generated with a random seed from another random number generator. This allows - the stdlib to use an OSRng to create seeded instances of these RNGs. -- Rand implementations for `Box<T>` and `@T` were removed. These seemed to be - pretty rare in the codebase, and it allows for librand to not depend on - liballoc. Additionally, other pointer types like Rc<T> and Arc<T> were not - supported. -- Remove a slew of old deprecated functions - - -## [Rust 0.10] - 2014-04-03 -### Changed -- replace `Rng.shuffle's` functionality with `.shuffle_mut` -- bubble up IO errors when creating an OSRng - -### Fixed -- Use `fill()` instead of `read()` -- Rewrite OsRng in Rust for windows - -## [0.10-pre] - 2014-03-02 -### Added -- Seperate `rand` out of the standard library |
