Cargo Features

fss-rs = { version = "0.4.3", default-features = false, features = ["full", "prg", "multi-thread", "group-int-be"] }
default = full

The full feature is set by default whenever fss-rs is added without default-features = false somewhere in the dependency tree.

full default = multi-thread, prg
prg full = aes

Affects dcf::prg, dpf::prg

multi-thread full = rayon

Features from optional dependencies

In crates that don't use the dep: syntax, optional dependencies automatically become Cargo features. These features may have been created by mistake, and this functionality may be removed in the future.

aes prg?
rayon multi-thread?
