Cargo Features

fastfield_codecs = { version = "0.3.1", default-features = false, features = ["bin", "unstable"] }
default = bin

The bin feature is set by default whenever fastfield_codecs is added without default-features = false somewhere in the dependency tree.

bin default = measure_time, prettytable-rs, rand
