Cargo Features

Barb has no features set by default.

[dependencies]
barb = { version = "0.4.3", features = ["jq"] }
jq = jq-rs

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.
