Cargo Features

VoluntaryServitude has no features set by default.

[dependencies]
voluntary-servitude = { version = "4.0.8", features = ["logs", "rayon-traits", "serde-traits"] }
logs = log
rayon-traits = rayon
serde-traits = serde

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.

log logs?
serde serde-traits?
rayon rayon-traits?
