Cargo Features

lmarkov has no features set by default.

[dependencies]
lmarkov = { version = "0.1.0", features = ["serialization"] }
serialization = serde, serde_json

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.

serde serialization?
serde_json serialization?
