Cargo Features

[dependencies]
surf_bucket_select = { version = "0.2.2", default-features = false, features = ["surf"] }
default = surf

The surf feature is set by default whenever surf_bucket_select 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.
