Cargo Features

[dependencies]
transfer-progress = { version = "0.1.2", default-features = false, features = ["bytesize"] }
default = bytesize

The bytesize feature is set by default whenever transfer-progress is added without default-features = false somewhere in the dependency tree.

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.
