-
Meta-features:
- nightly
-
some additions requiring nightly Rust
- serde
-
Enables serde and serde of rand_core
rand_core:
enables serde for BlockRng wrapper
- std default thread_rng = alloc
-
Option (enabled by default): without "std" rand uses libcore; this option enables functionality expected to be available on a standard platform.
Enables std of optional rand_chacha and rand_core
Affects
index::sample_weighted,slice::IndexedRandom.choose_multiple_weighted… - alloc std
-
Option: "alloc" enables support for Vec and Box when not using "std"
Affects
distribution::SampleString,distr::weighted,iterator::IteratorRandom.choose_multiple,slice::IndexedRandom.choose_multiple,slice::IndexedRandom.choose_weighted,slice::IndexedMutRandom.choose_weighted_mut,slice::SliceChooseIter… - os_rng default thread_rng
-
Option: enable OsRng
- simd_support
-
Option (requires nightly Rust): experimental SIMD support
- std_rng default thread_rng
-
Option (enabled by default): enable StdRng
Enables rand_chacha
- small_rng default
-
Option: enable SmallRng
- thread_rng default = os_rng, std, std_rng
-
Option: enable ThreadRng and rng()
Affects
rand::thread_rng,rand::random,rand::random_iter,rand::random_range,rand::random_bool,rand::random_ratio,rand::fill… - unbiased
-
Option: use unbiased sampling for algorithms supporting this option: Uniform distribution.
By default, bias affecting no more than one in 2^48 samples is accepted.
Note: enabling this option is expected to affect reproducibility of results. - log
-
Option: enable logging
Enables log
