Added

  • Imported functionality from std::rand, including:
    • StdRng, SeedableRng, TreadRng, weak_rng()
    • ReaderRng: A wrapper around any Reader to treat it as an RNG.
  • Imported documentation from std::rand
  • Imported tests from std::rand

[0.1.1] - 2015-02-03

Added

  • Migrate to a cargo-compatible directory structure.

Fixed

  • Do not use entropy during gen_weighted_bool(1)

[Rust 0.12.0] - 2014-10-09

Added

  • Impl Rand for tuples of arity 11 and 12
  • Include ChaCha pseudorandom generator
  • Add next_f64 and next_f32 to Rng
  • Implement Clone for PRNGs

Changed

  • Rename TaskRng to ThreadRng and task_rng to thread_rng (since a runtime is removed from Rust).

Fixed

  • Improved performance of ISAAC and ISAAC64 by 30% and 12 % respectively, by informing the optimiser that indexing is never out-of-bounds.

Removed

  • Removed the Deprecated choose_option

[Rust 0.11.0] - 2014-07-02

Added

  • document when to use OSRng in cryptographic context, and explain why we use /dev/urandom instead of /dev/random
  • Rng::gen_iter() which will return an infinite stream of random values
  • Rng::gen_ascii_chars() which will return an infinite stream of random ascii characters

Changed

  • Now only depends on libcore! 2adf5363f88ffe06f6d2ea5c338d1b186d47f4a1
  • Remove Rng.choose(), rename Rng.choose_option() to .choose()
  • Rename OSRng to OsRng
  • The WeightedChoice structure is no longer built with a Vec<Weighted<T>>, but rather a &mut [Weighted<T>]. This means that the WeightedChoice structure now has a lifetime associated with it.
  • The sample method on Rng has been moved to a top-level function in the rand module due to its dependence on Vec.

Removed

  • Rng::gen_vec() was removed. Previous behavior can be regained with rng.gen_iter().take(n).collect()
  • Rng::gen_ascii_str() was removed. 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 and Arc 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
