Cargo Features

[dependencies]
emerald-cli = { version = "0.23.0", default-features = false, features = ["cli", "dev"] }
default = cli

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

cli default = env_logger
dev = clippy

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 cli

Enables env_logger ^0.4
