We use cargo vendor to generate a .cargo/config file and the vendor directory. Vendoring allows us to lock our dependencies and to modify them easily from the top level Cargo.toml. We vendor all dependencies, including the crates.io ones, which allows for network isolated builds. Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>

- Include ChaCha pseudorandom generator
- Add
next_f64
andnext_f32

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 valuesRng::gen_ascii_chars()
which will return an infinite stream of random ascii characters
Changed
- Now only depends on libcore!
- Remove
Rng.choose()
, renameRng.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 onRng
has been moved to a top-level function in therand
module due to its dependence onVec
.
Removed
Rng::gen_vec()
was removed. Previous behavior can be regained withrng.gen_iter().take(n).collect()
Rng::gen_ascii_str()
was removed. Previous behavior can be regained withrng.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 ofread()
- Rewrite OsRng in Rust for windows
[0.10-pre] - 2014-03-02
Added
- Seperate
rand
out of the standard library
