Cargo Features

[dependencies]
dfs = { version = "0.1.1", default-features = false, features = ["build-binary", "logging"] }
default = build-binary

The build-binary feature is set by default whenever dfs is added without default-features = false somewhere in the dependency tree.

build-binary default = logging

Required by the binary

logging build-binary = env_logger, log

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.

env_logger logging?

Enables env_logger ^0.9.0
