Cargo Features

[dependencies]
libfmod = { version = "2.222.1", default-features = false, features = ["flags"] }
default = flags

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

flags default = bitflags

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.
