[features]
# Meta-features:
default = ["std"] # without "std" rand uses libcore
nightly = ["simd_support"] # enables all features requiring nightly rust

# Optional dependencies:
std = ["rand_core/std", "alloc", "getrandom"]
alloc = ["rand_core/alloc"]  # enables Vec and Box support (without std)
serde1 = ["rand_core/serde1", "rand_isaac/serde1", "rand_xorshift/serde1"] # enables serialization for PRNGs
# re-export optional WASM dependencies to avoid breakage:
wasm-bindgen = ["getrandom_package/wasm-bindgen"]
stdweb = ["getrandom_package/stdweb"]
getrandom = ["getrandom_package", "rand_core/getrandom"]

# Configuration:
simd_support = ["packed_simd"] # enables SIMD support
small_rng = ["rand_pcg"]    # enables SmallRng
