Cargo Features

[dependencies]
ddevmem = { version = "0.2.4", default-features = false, features = ["reg", "register-map", "device", "emulator"] }
default = device, reg, register-map

These default features are set whenever ddevmem is added without default-features = false somewhere in the dependency tree.

reg default
register-map default = concat-idents
device default = memmap2
emulator

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.
