Cargo Features

[dependencies]
breaking-attr = { version = "0.2.0", default-features = false, features = ["print_token_stream", "blake3", "sha2", "md5"] }
default = blake3

The blake3 feature is set by default whenever breaking-attr is added without default-features = false somewhere in the dependency tree.
