Cargo Features

lisp-rs has no features set by default.

[dependencies]
lisp-rs = { version = "0.3.5", features = ["build-binary"] }
build-binary = linefeed

Required by the binary

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.
